On Sunday I rescued a little guinea pig living in horrendous conditions. (All by himself, dirty cage, inadequate food, etc.) After a 500 mile drive home with our new little guy he still hadn't completely settled in. School starts Monday so today was the last day until middle of October I could get him neutered so he could be with my 2 girl piggies and no longer alone. He seemed to do well with the surgery and was healthier than we thought. Tonight though he's not eating, drinking, or pooping yet. If he doesn't start by the morning I was told to call, but I'm very anxious. Any tips or things to try? Unfortunatly he doesn't recognize any food except pellets and carrots currently.
