Pig crazy
Junior Guinea Pig


Ok Thankyou so much I was worried there for a second. I will take her next week if the toe hasnt fallen off by thenPolydactyly is a genetic condition that is well known with guinea pigs. You do not need to worry, but please see a vet for a safe removal if the toe is only loosely attached. She has already lost the extra toe on her other back foot.
