Honestly i didn't see any guinea pigs..I'd assume the same as the other animals but unfortunately just not sure. Sorry
It is the same as adopting any other animal. Adoption information is on their website.
call your local SPCA. ask if they have any guinea pigs available. if they do they will advise you of the qualifications needed to adopt a pet. hope it works out. every animal bird fish and reptile need a loving forever home
