Attitudes and Motivations of Owners Who Enroll Pets in Pet Life-Care Centers

The purpose of this study was to examine the characteristics, motivations, and expectations of humans who enroll their dogs, cats, and other pets into pet life-care centers. Pet life-care centers are groups or institutions that provide a permanent home for pets in the event of the owner’s illness, inability to care for their pet, or death. The long-term pet care industry has grown in the quality and type of care available to pet owners and is a classic example of the human–animal bond in action. This bond is well-documented in the literature, with most research focusing on physical, emotional, and mental health benefits to the pet owner. Few studies have examined how the human–animal bond affects the animal, and little is known about the motives and expectations of owners who enroll their pet in a life-care center. We conducted a study using a mail questionnaire sent to 163 current clients of a pet life-care center in Texas, USA. Of 101 respondents, whose ages ranged from 30 to over 70, most were female, married, and college-educated. Respondents strongly endorsed a variety of reasons for enrolling their pet in the center, with quality of veterinary care and satisfaction of their pet’s basic needs being the most highly rated. Coding of open-ended responses was consistent with these ratings and identified having no other options as another frequently endorsed reason. The open-ended responses also indicated that respondents expected that their pet would enjoy extensive social interaction, receive high-quality medical attention, and be treated like they were at home. Respondents who had previously visited the center were more willing to adopt a pet in the future than those who had not visited the center. With the dramatic growth of pet life-care centers in the United States and lack of existing literature, further studies in this area are advised.     

Influence of expression of the pet operon on intracellular metabolic fluxes of Escherichia coli

Fermentation patterns of Escherichia coli HB101 carrying plasmids expressing cloned genes of Zymomonas mobilis pyruvate decarboxylase (PDC) and alcohol dehydrogenase li (ADH) were determined in glucose-limited complex medium in pH-controlled anaerobic batch cultivations. Time profiles of glucose, dry cell weight, succinate, formate, acetate, and ethanol were determined, as were the activities of ADH and PDC. Fluxes through the central carbon pathways were calculated for each construct utilizing exponential phase data on extracellular components and assuming quasi-steady state for intermediate metabolites. Overall biomass yields were greatest for cells expressing both PDC and ADH activities. Yields of carbon catabolite end products were similar for all PDC-expressing strains and different from those for other strains. Relative to its glucose uptake rate, the strain with greatest PDC and ADH activities produces formate and acetate more slowly and ethanol more rapidly than other strains. Strong influences of plasmid presence and metabolic coupling complicate detailed interpretations of the data.     

The use of ruminant models in biomedical perinatal research

Animal models are of critical importance in biomedical research. Although rodents and lagomorphs are the most commonly used species, larger species are required, especially when surgical approaches or new medical devices have to be evaluated. In particular, in the field of perinatal medicine, they are critical for the evaluation of new pharmacologic treatments and the development of new invasive procedures in fetuses. In some areas, such as developmental genetics, reproductive biotechnologies and metabolic programming, the contribution of ruminants is essential. The current report focuses on some of the most outstanding examples of great biomedical advances carried out with ruminant models in the field of perinatal research. Experiments recently carried in our research unit using ruminants are also briefly described.     

A Systematic Review of Research on Pet Ownership and Animal Interactions among Older Adults

ABSTRACT

Research on the impact of companion animals in the lives of older adults is considered from two perspectives: pet ownership and in animal-assisted interventions (AAI). This paper first presents a discussion of potential theoretical explanations of the impact of animals on human health and wellbeing among older adults, and then provides a systematic review and evaluation of existing research on the topics of human–animal interaction (HAI) and physical health and exercise, depression and anxiety, and loneliness and social functioning. Each of the studies in this review (n = 145) are rated according to modified Oxford Center for Evidence Based Medicine (OCEBM) levels and the role of theory, in conceptualizing the study or interpreting outcomes, is discussed. The quality of evidence for each topical area of HAI and aging research is summarized, and recommendations are made for future research directions that will increase our knowledge of the relationship between HAI and health outcomes for older adults in different settings.     

Sex differences in the antecedents of animal use attitudes

Abstract

Sex differences in attitudes toward the use of animals have been reported in previous research. This study examines sex differences in the levels of, and the interrelations among, three potential antecedents of attitudes toward animal use: caring value orientation, pet care experience and attachment to pets. Path analysis showed that pet care experience, through attachment to pets, accounted for a significant portion of variance in animal use attitudes in both males and females. Caring value orientation was directly linked to animal use attitudes in females, but in males, caring value orientation affected attachment to pets, which in turn impacted on animal use attitudes. Results are discussed in terms of Gilligan's theory of socialization.     

Attitudes toward Animals of Students at Three European Veterinary Medicine Schools in Italy and Spain

The European Veterinary Code of Conduct recognizes the crucial role of veterinarians in improving animal welfare and maintaining its standards. However, several studies have claimed that veterinary students’ attitudes toward animals may worsen as they progress through their academic training. This study aimed to investigate students’ attitudes toward nonhuman animal use in three European veterinary medicine schools (Italy and Spain). For this purpose, 565 veterinary students completed a questionnaire consisting of a range of items grouped into four animal-use categories: “Research,” “Entertainment,” “Utilitarianism,” and “Veterinary Issues.” Items were scored on a 5-point Likert-type scale, with higher scores indicative of higher concern regarding animal welfare. Results showed that the use of animals for “Entertainment” and questions related to “Veterinary Issues” raised the most concern among the veterinary students, while the use of animals for “Research” was of least concern. Moreover, we also examined some potentially confounding factors: age, academic year (first to fifth), gender, previous experience with pets, and university. Female students had a higher concern for animal welfare compared with their male counterparts. Students in their earlier stages of training as veterinarians also exhibited a greater concern for animal welfare compared with those of later academic years. Other factors affecting students’ attitudes toward animal use were the age of the students and the university they were enrolled at. The findings of this study confirm that attitudes toward animal use are not homogeneous and are associated with students’ demographic, educational, and personal characteristics.     

The use of new world primates for biomedical research: an overview of the last four decades

Animal experimentation contributes significantly to the progression of science. Nonhuman primates play a particularly important role in biomedical research not only because of their anatomical, physiological, biochemical, and behavioral similarities with humans but also because of their close phylogenetic affinities. In order to investigate the use of New World primates (NWP) in biomedical research over the last four decades (1966–2005), we performed a quantitative study of the literature listed in bibliographic databases from the Health Sciences. The survey was performed for each genus of NWP that has been bred in the National Center of Primates in Brazil. The number of articles published was determined for each genus and sorted according to the country from which the studies originated and the general scientific field. The data obtained suggests that Brazil is a leader in generating knowledge with NWP models for translational medicine. Am. J. Primatol. 72:1055–1061, 2010. © 2010 Wiley‐Liss, Inc.

Sociodemographics of Pet Ownership among Adolescents in Great Britain: Findings from the HBSC Study in England,Scotland, and Wales

The aim of this study was to assess the prevalence of pet ownership among adolescents in Great Britain and identify any sociodemographic differences between pet owners and non-pet owners. A total of 14,328 11-to 15-year-old adolescents from England, Scotland, and Wales were included in the analysis. Results revealed 15-year-old adolescents were significantly more likely than 11-year-old adolescents to own dogs (OR = 1.146, p < 0.001) but less likely to own fish, reptiles, or amphibians (OR = 0.629, p < 0.001), and small mammals (OR = 0.630, p < 0.001). Thirteen-year-olds were significantly more likely than 11-year-olds to own dogs (OR = 1.240, p = 0.021) and birds (OR = 1.299, p = 0.010), but significantly less likely to own fish, reptiles, or amphibians (OR = 0.795, p < 0.001). No gender differences were found. White adolescents were more likely than non-white adolescents to own all pet types. Those living in single-parent families were significantly more likely than those living with two parents to own dogs (OR = 1.186, p = 0.013) and cats (OR = 1.319, p < 0.001). Furthermore, those who reported living in stepfamilies were also more likely to own cats (OR = 1.428, p < 0.001). Adolescents with siblings were more likely to own cats (OR = 1.391, p = 0.001), fish, reptiles, or amphibians (OR = 1.220, p = 0.037) than adolescents without siblings. Adolescents with employed parents (both or one) were significantly more likely than those with unemployed parents to own dogs (OR = 1.414, p = 0.002) and birds (OR = 1.523, p = 0.018). Adolescents from high-affluence families were less likely than adolescents from low-affluence families to own dogs (OR = 0.888, p = 0.037), small mammals (OR = 0.832, p = 0.005), and birds (OR = 0.801, p = 0.046). Furthermore, family affluence differences were found in different pet types. Differences in all pet types and siblings were also found in a proxy measure of attachment to pets. This study provides evidence that pet ownership is related to several sociodemographic factors. These are relevant to take into account when performing HAI studies on adolescents.     

Attitudes in China toward the use of animals in laboratory research

Public support is a strong impetus for the adoption of alternatives to laboratory animals. It is therefore important to find out what a society thinks about ethical animal use. In the case of China, a useful line of enquiry was to survey Chinese people's as their country is renowned for the deplorable conditions under which animals are kept. This report concerns an investigation into the attitudes of Chinese university students toward the use of animals in laboratory research. The survey revealed a moderate concern amongst students; for example, they agreed that the use of animals for testing cosmetics and household products is unnecessary and should be stopped, and disagreed that humans have the right to use animals as they see fit. This finding is very encouraging. Further research is needed, in order to understand Chinese views about the justification of using animals in research.     

Opinions of UK Rescue Shelter and Rehoming Center Workers on the Problems Facing Their Industry

Animal shelters exist worldwide to care for and rehome unwanted or straying pets. Previous studies have examined why owners breed unwanted animals, or relinquish their pets to shelters. However, the views of shelter workers, who receive and care for these animals, have previously been largely unexplored. The aim of this study was to investigate the perceptions of animal shelter workers on the problems facing their industry. A sampling frame was constructed, consisting of every identified shelter in the UK, and a postal questionnaire sent to each. This included two open questions, soliciting respondents’ views on their biggest problems, and inviting further comments. A total of 661 respondents replied to at least one question. Thematic analysis on the free text content was carried out, and basic and global themes identified. Respondents’ main concerns centered on a mismatch between the continuous demand for their services and their limited resources, which has worsened during the recent financial crisis. Respondents perceived a need for increased public awareness of the commitment involved in keeping a pet, and of controlling breeding by neutering. Points of intervention, such as education programs, were suggested. Coordinating efforts with others, including local authorities, landlords, and housing associations, and a potential role for veterinary professionals working in shelter medicine were all explored by respondents. Rehoming organizations play an important role in the management of pet overpopulation, and the views and beliefs of their workers form an important contribution to the dialogue surrounding this issue. Consideration of these perspectives may suggest alternative routes to address underlying causes and management of pet overpopulation.
