Teddy is Jennie's almost-2-year-old hamster, which I know is old for a hamster. Last week when we cleaned his cage I noticed quite an odor about him and the cage, so I gave him a quick bath using a drop of dog shampoo and holding him in my hand to minimize trauma. He seemed to take it well and fluffed up nicely, BUT I noticed while I was bathing him that his tummy was almost hairless and seemed a bit scabby.
Last night he was walking around his cage kind of hunched over, like he's favoring his tummy. It doesn't look any worse, but I dabbed a little olive oil on it to see if that would moisturize the skin a bit. (He immediately started washing himself and darting dirty glances at me, but I figured a little olive oil wouldn't hurt him.) I saw online that tea tree oil could also be used, so I may try that tonight.
He's just not himself -- he'll eat the carrots we put in but his food dish isn't getting emptied as fast as before. Seems to be drinking enough water.
I think it's old age -- there's no indication of mites and no place he could pick up ringworm (the other two alternatives).
Anybody have advice for me? We can't really afford to take him to the vet right now, and if it IS old age there's nothing to be done for him anyway.
