Cat experts! Help needed (update on abandoned cat)

[artifactos]

Two things I noted from your posts about this cat: he is very underweight and he drinks a lot. Those COULD be signs that he is diabetic - you may want to have a vet check for that. I had a barn cat that developed diabetes as he aged, and he suddenly lost a TON of weight, drank constantly (and ate a ton, but puked a lot of it back up), and peed a lot. He didn't respond well to insulin injections and had to be put down.

Edit: I'm not sure these points apply anymore, since he looks pretty healthy in that picture, but I figured I would leave the note anyway. I might not be comprehending very well, either, after a long and tiring weekend.

Otherwise, he's a cutie and I hope he gets along with your pets soon! Good for you for looking out for him!
