My cat is two years old and neutered. Tonight he started being more vocal than usual - but it didn't sound like his usual meow, it sounded more like a cry. We thought he needed some attention so we played with him and pet him. Then we noticed that some sort of discharge was coming out of the scar where he was neutered. It's Saturday night and our vet doesn't open until Monday morning. Does anyone know what it is and should we go to the 24-hour animal hospital? I called and they said they couldn't tell me over the phone whether or not I should come in. He's sleeping now, which makes me less concerned. Advice? Thanks.
