Rehoming Laboratory Rats: Exploring Perceptions of Rehomers, Animal Technicians, and Biomedical Researchers.

Humans work with animals in many different ways. In some contexts, animals are allowed to 'retire' and be rehomed in sanctuaries or private homes when they are no longer able or needed to work. Similarly, laboratory animals can be rehomed at the end of a study. However, there is relatively little research on stakeholders' perceptions of rehoming. We explored the views of three key groups: the people who adopt these animals, the animal technicians who care for these animals prior to rehoming, and the researchers who are normally responsible for most of the interactions between people and these animals. To do this, we carried out a thematic analysis of semistructured interviews. Our aim was to obtain insights that could inform reflection and guide future research priorities around rehoming programs. Our study demonstrated support for laboratory rat rehoming in all stakeholder groups. Rehomers' and technicians' comments focused chiefly on the potential benefits of rehoming to the animal and benefits to institutional openness. Researchers made similar comments, but these were tempered by concerns around the welfare of the animals after rehoming, the fate of animals that cannot be rehomed, rehomers' health and wellbeing, and the potential risks associated with the transparency of individual's and the institution's use of animals in research. We discuss these themes in the context of the ethics of laboratory animal use, manifesting a culture of care, and challenges around enhancing institutional openness on animal research.
