You might remember this outfit from an episode of South Park.
Come talk to Scuzzy here: [link]
EDIT: I was worried I'd get negative comments so I want to clear things up before I receive anymore. This costume was specifically made for guinea pigs, thus they were created to be as comfortable as possible for them. This doesn't mean every guinea pig will be receptive to wearing them and I don't support forcing any animal into an outfit just for a cute photo. Scuzzy is incredibly laid back and didn't care at all; he was just happy for attention. No harm came to him at all and I don't keep him in costume for long. If he had put up a fuss this photo wouldn't exist. I love my pet and do all I can to make sure he is happy.
