Establishing New Isosexual Pairs in Adult Male Guinea Pigs () to Facilitate Social Housing.

Guinea pigs () are a commonly used species in biomedical research. As social creatures, compatible guinea pigs should be housed together unless scientific objectives or veterinary care require otherwise. Extensive literature suggests that adult male guinea pigs are highly aggressive in the presence of females, but data are lacking regarding the compatibility of cohoused adult males in the absence of females.
