Gosh, I'm sorry to read about the troubles you're having with Panther. It sure seems like there is something going on, so I hope your vet can diagnose it quickly so treatment can begin. A one pound loss is a lot for a cat, so it's very understandable how worried you are.

Have you tried kitten formula? This might help if he's not eating, so he can at least continue to get some nutrients. Are you able to force-feed with the dropper ok?

Pedialyte is another thing that some folks try when their animals aren't eating.

I certainly hope they can find out what's wrong with Panther, and soon!

**hugs**
