So are we!
That's the thing with hamsters - they scarf up seeds into their pouches so you think they're eating. His food was disappearing out of his food bowl every day. I just totally cleaned out his cage and found out where he had been carrying it off to. He's going to be a little upset when he comes home to fresh bedding and no huge stash! (I left him some stinky bedding and a small stash to carry him over....)
He has had quite a number of chew toys, none of which he has used. I wonder if that tooth has been preventing him from gnawing properly? I just daubed a bit of butter on his seed log (a chew log) in the hopes that he'll lick it off and then gnaw at the seed log itself. Although he may not feel like gnawing much today. (Or he could have the munchies - he is stoned right now, after all!)
Anyway, with old hamsters it is not uncommon for them to lose weight and slow down. He was otherwise alert and affectionate, and nothing seemed amiss that couldn't be attributed to normal old age - cateracts, moving more slowly, sleeping more, that kind of thing. I wouldn't have caught this except that I had asked the daughter a few times to check his teeth and she couldn't get a good look at them, but thought they were fine. Finally we were able to pin him in such a way that we could see into his mouth from the side and we both spotted a tooth that seemed to be curved that should have been straight. If you'd have looked in his mouth from his right side, all was good. It was only looking in from the left side of his face that we spotted the problem. Even the vet couldn't tell until Lemon was in happy-gas-land how bad it was. Poor little guy. Well, he should be feeling much better now. They said he was begging for treats already.
Geez, this bill is gonna sting, too, with the pain meds and the antibiotic on top of the vet exam and procedure supplies. (sigh) Thankfully I got part of my IRS tax return last week. That oughta just about cover it.
