I was bathing my guinea pig 2 days ago and I noticed a very red, split bump on the left side of his lower belly, right above his nipple. It doesn't seem to bother him, He is still eating/drinking and playful,
he doesn't squeal or seem uncomfortable when I touch it or move it around, but I am extremely concerned. I don't know if I will be able to get him to a vet, right now money is extremely tight for me. Does anyone know if this is something I can treat from home? (I have attached a picture)
