Poor bugger. It looks bad, though he doesn't even seem to be taking particular note of it. I wonder whether it's interfering with his peeing.
It didn't interfere with his deciding to take a giant leap over a barrier so he could explore the dining room and kitchen. And then walk around meowing about everything he found there, like he did with the living room last night.
If I take him to the Humane Society clinic, his first exam is discounted, and there's a cheap co-pay for any needed medication if it's within 10 days of adopting him. So maybe I can get in there first thing tomorrow. If not, it'd be regular hours at the walk-in vet, and paying more. But not as much as overnight vet costs.
I'm trying to imagine how they'll deal with it. Is this a stitch-up situation? Can you bandage a cat's belly? Will he get one of those neck cones to keep him from futzing with it? I don't think he'd care much for that. It would be hard to get into his little room on the cat tree.
