Social isolation and loneliness are concerns in gerontology. The impact of the human–animal interaction (HAI) on loneliness for older adults living alone is understudied. This scoping review explored the extent to which HAI is included in studies investigating social connectedness, specifically social isolation and loneliness, and if HAI bolsters healthy aging through increased perceived support. Following the PRISMA-ScR protocol, data from 58 articles were thematically categorized, identifying (a) existing inclusion of HAI; (b) definitions and descriptions of HAI; and (c) the relationships between HAI and loneliness outcomes, in social connectedness research. Studies including HAI (animal companions and animal-assisted interventions) have increased over time; many noting protection against loneliness and few noting health detriments. Older adults overwhelmingly consider interactions with companion animals as meaningful relationships, whether living at home or in care. Substantial knowledge gaps exist concerning the influence of HAI on perceived social connectedness for older adults living alone.

Pet guardianship is a common practice globally that enhances human well-being by offering companionship and emotional support. However, it also entails financial responsibilities that can pose challenges to both human and animal well-being. This study used an online survey distributed between January and March 2019 to adults residing in Aotearoa New Zealand (NZ), to investigate financial aspects of pet guardianship, including the importance of pet insurance, the impact of veterinary costs, and the ethical considerations of owning a pet. Understanding these aspects is crucial for promoting responsible pet ownership and ensuring animal welfare. Data were collected through a nationwide online survey, part of the Furry Whānau Wellbeing research project. The survey included questions regarding the financial aspects of pet guardianship, and respondents were asked to indicate their level of agreement with various statements. A total of 2,744 respondents participated in the survey. Of these, 2,358 respondents answered the pet guardianship section. Among them, 885 (37.5%) owned both cats and dogs, 652 (28%) were cat-only owners, 609 (26%) were dog-only owners, and 212 (9%) did not currently own a cat or dog. The cost of veterinary care was identified as a key concern, with 1,924 out of 2,296 (83.9%) respondents agreeing that the expense affects the level of healthcare their pets receive. Only one-third of respondents (825/2,296) considered pet insurance essential due to high costs and exclusions. The study also revealed disparities for rural and low-income households. The financial well-being of pet guardians presents a complex challenge, affecting both the well-being of the pet and its owner. This research highlights the need for comprehensive strategies to promote sustainable and equitable pet guardianship, including improving access to affordable veterinary care, enhancing financial literacy among pet owners, and providing support systems for those facing economic hardship.

The aim of this study was to examine the presence of tick-borne rickettsial bacteria in Rhipicephalus sanguineus sensu stricto ticks collected from dogs in the Patagonian region of Argentina. Fourteen stray dogs from Valcheta, Río Negro province, Argentina were examined for the presence of R. sanguineus s.s. ticks. Ninety ticks were collected and identified to species level. DNA was extracted and analysed by conventional PCR assays for the presence of tick-borne bacteria belonging to the genera Anaplasma, Ehrlichia and Rickettsia. Thirty-three tick pools were tested by different PCR assays of which 3 were positive for Anaplasmataceae bacteria. From the 3 Anaplasmataceae positive samples, 2 partial 16S rDNA sequences were generated and belonging to Anaplasma platys, the causative agent of canine cyclic thrombocytopenia. Two tick samples were positive in Rickettsia specific PCR assays and were identified by phylogenetic analysis as Rickettsia massiliae, a member of the spotted fever group rickettsiae. The results of this study demonstrate the molecular detection of 2 rickettsial bacteria in R. sanguineus s.s. in a region of Argentina where no data were available so far.

Animal welfare offences encompass a heterogeneous range of crimes, including violence and various forms of negligence toward animals’ needs. However, there is limited understanding of the offenders’ rationalisations concerning their criminal behaviour against animals, despite this information being essential for enhancing the prevention of these crimes. Our data comprised 1,443 judgements in animal welfare offences in Finland between January 2011 and May 2021. We categorised the rationalisations used by defendants and identified differences between offender profiles according to the offence type. Nearly all defendants responded to the charges. Overall, defendants appealed most often to their challenging circumstances, e.g. a lack of resources. Defendants charged with offences against production animals offered more explanations than the other defendants and often denied their responsibility for the animals, or having caused them any harm, and appealed to financial problems, weather conditions, and having too many animals. Moreover, they frequently challenged the norms, appealing in particular to the immorality of the authorities, who were mostly official veterinarians. Defendants charged with animal hoarding offences rationalised their actions similarly to animal farmers, whereas those charged with violent crimes against animals more often cited provocative or otherwise problematic behaviour of the animal victim. Our results support the observation that farmers may perceive official animal welfare supervision negatively. Violent animal welfare crimes and animal hoarding stand out as distinctive types of crime at the level of rationalisations. The differences between offence types and offenders’ underlying motivations should be considered when developing animal welfare control, agricultural support systems, and crime prevention.

Drawing upon data from a study examining experiences of accessing support for pets from the UK animal welfare charity Blue Cross, this paper illuminates reasons why people might not seek support when they need it. This applies to those who are struggling financially and are eligible for, but do not take, free/reduced cost veterinary care, or are having other problems (e.g. the animal’s disruptive behaviour or ill health, struggling to care for the pet due to changing circumstances or health problems, or coping with pet loss). Twenty Blue Cross service users (15 female, five male, age 29–67) took part in individual online interviews using a semi-guided narrative approach, where they were encouraged to share their experiences of reaching out. They were also asked to reflect upon why others may not do the same, and if they had any recommendations for organisations to help them reach these people. Findings echo other studies that highlight a fear of being judged, disclosure and stigma. Guilt, shame, lack of awareness, financial concerns, and wanting to manage independently, all play important roles. These factors have implications for the way support services are advertised and delivered to ensure animals receive the care needed. We describe these reflections and recommendations and identify three broader ideological narratives underpinning participants’ stories: ‘giving back’; ‘equity’, and ‘sacrifice’. These reveal how wider societal attitudes and values shape identities and behaviours. It is vital that support on offer is reframed to explicitly counteract these influences to ensure optimal animal and human welfare.

Companion animals, or ‘pets’, are integral to many people's lives and to their sense of home. However, older people living with companion animals are vulnerable to separation from their animals when moving to a care home. Such separation is often a highly significant loss which, combined with other losses, may reinforce experiences of dislocation. Existing research draws attention to the importance of developing a sense of ‘home’ in a care home through reinforcing and preserving personal connections. However, there is a paucity of research examining the preservation of connections between older people resident in care homes and their animal/s. This study draws on thematic analysis of 29 qualitative interviews with older people living in care homes, relatives, care home staff and other relevant stakeholders. It highlights that retaining existing, often long-term, bonds with companion animals represent important continuities and connections which may contribute to positive adjustment to life in a care home and creating a sense of home. However, participants highlighted that supporting an older person to move into a care home with their companion animal may be challenged by real or perceived constraints such as use of shared space, concerns about the risks posed by animals and staff implications. While our study found examples of good practice of how shared residence between an older person and companion animal can be achieved in a care home, other examples highlighted that the time, complexity of planning and structures required to accommodate animals were prohibitive to merit a change of policy and practice. Our research concludes that more attention should be given to the older person–animal bond as an important source of continuity and connection.

Relationships with companion animals, or “pets”, may promote health and well-being for older adults as they age-in-place. Less is known, however, about ways that pet-related challenges may simultaneously influence aging-in-place experiences. This study explores the relational qualities of having pets later in life by considering qualitative accounts of older adults who are aging in the community. Semi-structured interviews with 14 socio-economically diverse, community-dwelling older adult pet-owners (≥ 60 years) living in Calgary, Alberta, Canada, were analyzed reflexively. Four recurring themes suggested that companion animal relationships were valued in older adults’ lives and helped them cope with challenging circumstances, even when pets were central to these challenges. Findings also confirmed the relational nature of human-animal relationships as being shaped by both individual attributes and systemic factors. Methodological approaches to addressing these multifaceted complexities when studying pets and aging are considered. Enhanced cross-sectoral community and policy-level supports for aging-in-place with pets may have a population-level influence on health, well-being, and social justice across the socio-demographically diverse aging population.

As animals experience distress in animal shelters, leaders call for increased efforts to divert intake of companion animals away from shelters. One novel intake diversion strategy is supported self-rehoming, where owners find new homes for their animals without surrendering to a physical shelter. This study aimed to identify predictors of successful diversion of animals through the AdoptaPet.com ‘Rehome’ online platform. Data for dogs (n = 100,342) and cats (n = 48,484) were analysed through logistic regression to assess the association of animal- and owner-related factors and outcome. Overall, 87.1% of dogs and 85.7% of cats were successfully diverted from animal shelters, out of which, 37.8% of dogs and 35.3% of cats were kept by their original owner. Multiple animal-related factors predicted increased odds of diversion (e.g. younger, smaller). Dog and cat owners who set a longer rehoming deadline (i.e. > 8 weeks) were over twice as likely to keep or adopt out their animal. Dog owners who surrendered for owner-related reasons had increased odds of diversion in comparison to animal behaviour issues. We conclude that online-supported, self-rehoming platforms provide pet owners with an alternative to relinquishment that may reduce the intake of animals to shelters; however, owners with animals that are not preferred by adopters may have to decide whether to keep their animal or relinquish their animal to a shelter or rescue. These results provide guidance for animal shelter professionals on the likelihood of successful diversion programmes given certain animal and owner characteristics.

In recent years there has been an increased interest in studies related to the welfare of avian species commonly kept as companion animals, specifically those in the order Psittaciformes, commonly referred to as ‘parrots’. During this time the biology and behaviour of wild parrots has also become better understood, aiding the assessment of welfare in captive environments. The impact of the pet trade on wild parrot populations has also become clear. This order now has more globally threatened species than almost any other major group of birds. Many significant aspects of parrot behaviour in the wild, such as flocking, social interaction with conspecifics, foraging on a variety of foods and flight, are denied to varying degrees to parrots kept as companion animals. Captive parrots show high levels of stereotypy, suggesting poor welfare. Welfare may be improved by appropriate environmental enrichment and changes in the social environment of captive parrots kept as companion animals; however, such changes require that caretakers have sufficient knowledge, resources and motivation to accommodate such conditions. The concept of companion animal suitability is an important consideration when developing regulations or policy aimed at improving the welfare of animals kept as companions. Although individual exceptions exist and the level of suitability may vary depending on species, in general, their presence in the pet trade has resulted in serious animal welfare and conservation challenges for parrots, indicating that these animals may be unsuitable as human companions.

Much of my research has been devoted to determining the cognitive and communicative abilities of Grey parrots (Psittacus erithacus), but other companion animals and those in captivity in Zoos also have considerable capacities that are often under-utilised in such settings. Many such animals are left to their own devices for large parts of the day; their boredom may translate into unsuitable behaviour patterns. In order to address this problem, my colleagues and I began to devise various computer-based ‘toys’ that would not only provide enrichment in the sense of relieving boredom and reproducing situations somewhat like the challenges faced by animals in the wild on a daily basis, but also would help us determine the extent of these animals’ cognitive capacities. Some of these systems allow remote interactions between owners and their pets and others might be adapted for animal-animal interactions. In this paper I will describe these projects, their aims, and our limited progress.

Municipal regulations and humane movement policies often restrict or discourage the use of ‘exotic’ species as companion animals. However, confusion arises because the term ‘exotic’ is used in various ways, and because classifying species as exotic or non-exotic does not satisfactorily distinguish suitable from unsuitable companion animals. Even among commonly kept species, some appear to be much more suitable than others. Instead, decisions about suitable companion animal species need to be based on a number of relevant issues. As ethical criteria, we considered that keeping a companion animal should not jeopardize - and ideally should enhance - its welfare, as well as that of its owner; and that keeping a companion animal should not incur any appreciable harm or risk of harm to the community or the environment. These criteria then served as the basis for identifying and organizing the various concerns that may arise over keeping a species for companionship. Concerns include how the animals are procured and transported, how well their needs can be met in captivity, whether the animal poses any danger to others, and whether the animal might cause environmental damage. These concerns were organized into a checklist of questions that form a basis for assigning species to five proposed categories reflecting their suitability as companion animals. This assessment framework could be used in creating policy or regulations, and to create educational and decision-making tools for pet retailers, animal adoption workers, and potential owners, to help prevent animals from being placed in unsuitable circumstances.

It is generally accepted that to carry out certain trials or procedures, particularly metabolism or digestibility studies, it is necessary to house animals singly, often in sterile metal cages which differ greatly from the animal's normal living accommodation. The lack of choice, mental and physical stimulation and general ‘creature comforts’ increases the stress of isolation.

The design of the buildings at the Waltham Centre for Pet Nutrition aim to ameliorate these unsatisfactory conditions and provide environmental enrichment, freedom of choice and mental and physical stimulation, in housing as similar as possible to the normal housing of domestic pets.

An international panel of experts in the fields of canine and feline health, welfare and behaviour conducted an online discussion addressing two questions: (1) how can one define quality of life (QoL) for dogs and cats in confined living situations, such as laboratories; and (2) what additional research is needed to determine how optimal QoL can be achieved? The panel suggested that QoL encompasses animal welfare and the subjective ‘feelings’ of the animal regarding its life, and that it can only be inferred from behavioural, physiological and other measures. Two methods for measuring QoL were proposed: establishing an ethogram defining QoL for individuals; and developing a ‘quality of living’ scale that can be applied to facilities housing groups of dogs and cats. Constructing these measures requires a comprehensive research program, and the paper discusses overall research objectives, specific questions that must be addressed, and some proposed research methods.

In Organisation for Economic Co-operation and Development (OECD) countries, the number of pets and pet owners has been increasing in recent years. The experiences people have with pets might impact their relationships with animals in general and especially attitudes towards animal protection and use. However, research on the impact of pet ownership on values and attitudes towards animals is relatively scarce. We analyse associations of pet ownership with different values and attitudes towards animals. We derived seven attitude constructs towards animals from three different datasets using Principal Component Analyses. Data were collected using standardised online surveys with German residents (dataset 1 = 1,049 respondents; dataset 2 = 414 respondents; dataset 3 = 1,048 respondents). All three samples are non-probability quota samples. The seven attitudinal constructs represent values and attitudes towards animals ranging from general values and attitudes towards, eg animal protection, to more specific attitudes towards, eg eating animals. We analysed the relationship of pet ownership, sex, and age with these constructs using ANOVA. Our results show that effect sizes are small to medium. Pet ownership has the strongest association with more general values and attitudes towards animals, with pet owners being, eg more involved in animal protection and more in favour of awarding fundamental rights to animals. In contrast, we found that more specific attitudes, such as the evaluation of current pig farming systems or attitudes towards eating meat, were more related to sex than pet ownership. Our findings indicate that having pets relates to their owners’ attitudes towards animals, but that this association varies depending on the specificity of attitudes.

Qualitative Behaviour Assessment (QBA) is used to assess animals’ emotional expressions and its potential for serving as an indicator of temperament has been explored. This method is open to assessors’ interpretation and it is therefore necessary to evaluate the observers’ reliability for different species and contexts. We aimed to assess the intra- and inter-observer reliability of QBA as an indicator of cat (Felis catus) temperament. The QBA was applied by 19 observers with divergent profiles of contact with cats (cat owners vs non-owners) and experience in behavioural assessment (experienced vs inexperienced). Forty-two, 12-min videos were assessed, composed of footage of four behavioural tests: unfamiliar person, novel object, conspecific reaction, and food offering tests. By using Principal Component Analysis, we found three principal components (PC) that were considered the main dimensions of cat temperament. According to Kendall's coefficient of concordance, intra-observer reliability was high to very high in PC1 (0.80-0.90) and moderate to high in PC2 and PC3 (0.50-0.82). Inter-observer reliability for the 19 observers was high in PC1 (0.71) and low in PC2 and PC3 (0.21-0.29). The individual concordances with the gold observer (defined based on greater experience with the QBA) ranged from moderate to high. We concluded that QBA could be a reliable tool to assess cat temperament, given the high values of intra- and inter-observer reliabilities in PC1, which is the dimension that most explains the behavioural variations in the cats’ temperament. The same did not occur for PC2 and PC3, showing that reliability varied among the different dimensions and observers.

The ability to evaluate the welfare of non-human animals accurately and objectively is influenced by a variety of factors including the nature of our relationships with them. Subjective biases in the perception of an animal's quality of life can have either positive or negative consequences for its welfare and are likely to be particularly exaggerated in the case of companion animals, such as dogs, cats and other pet species, with which people tend to form strong anthropomorphic, attachment-based relationships. The consequences of these subjective biases are likely to be further exacerbated by the fact that many of the physical and behavioural attributes that humans find appealing, and have selected for, in companion animals, are inherently detrimental to their welfare. Using a range of examples, this paper explores some of the complex ways in which anthropomorphism and subjectivity can cloud our ability to make reliable judgements concerning the welfare of companion animals, even in the face of seemingly obvious and overt indicators of pain and suffering.

The objective of this study was to assess whether pet ownership contributes to social participation and life satisfaction for older adults. We used baseline data from the Canadian Longitudinal Study on Aging (CLSA) for this purpose, and logistic regression models to estimate associations between social participation and life satisfaction for pet owners and non-owners. One third of all older adults (≥ 65 years, n = 7,474) in our sample reported pet ownership. Pet owners were less likely than non-pet owners to report life satisfaction and to participate frequently in social, recreational, or cultural activities, but pet owners were no less satisfied than were non-owners with their current levels of social participation. For pet owners experiencing barriers to social participation, pets appeared protective of life satisfaction in some circumstances. Both individual characteristics and structural factors linked to the World Health Organization’s age-friendly communities framework were relevant to understanding these findings.
