I, too, have an older cat that is losing weight. My income is being stretched very thin right now, so vet visits are not possible. Mac is eating well and getting his share (he's Alpha Cat in my house) and playing and causing mischief as much as ever. Soooo, I've decided to give him bigger portions and allow him some snacks. He looks and acts healthy, but I know from experience, some older cats just lose weight. I think Scooter Bug will be okay until you can get him to the vet. I now check Mac's water intake and it hasn't increased at all. He doesn't eat any differently than he ever did, so I'm thinking it's just age. I can live with that. He's only about 13, but I guess that can be considered a senior cat.
