Hi guys- I'm a fairly new cavy owner. We live in Montana. Appa has long white hair. I've had my pig for about 6 months. He's about a year old now. I took him to the vet last week because his bottom was swollen and sticky. I was told it was the oil gland that was a little infected. We've been doing warm compresses and topical antibiotics. All of the stickyness has disapeered but his bottom is still a bit swollen. Now it is on either side of his penis. Is it likely just his testicles? I thought he'd be done with puberty by the time I got him at roughly 6 months. It seems odd that his balls would drop now. Thoughts?
