litter permanently stuck to cat's skin
I have what I guess is an unusual circumstance I can't seem to find any advice about. We have two cats, both about fifteen years old. They were litter-mates, but one was a short-hair and the other a long-hair. We've used clumping cat littler for a long time. It seems to work well with no problems for our cats, until now.
My wife noticed our long-haired cat seemed to be walking a bit slower, not climbing around as much for a couple of days. When she picked her up and examined her she noticed there was some clumping cat-litter stuck to her fur on her belly near her bottom. It seemed to actually be restricting the motion of her hind legs. She tried to brush it out, but it's totally stuck to her fur, almost like cement. I tried bathing her, using cat-shampoo and then hydrogen peroxide, and then I applied some antiobiotic-plus-pain-relief cream, which gave her some temprary relief, but nothing seems to really dissolve it. We of course stopped using the clumping litter for her, but her mobility is getting worse, almost like the hide of her upper hind legs are glued to her belly, which pulls her skin when she walks.
I tried to shave it off, but it's too close to her skin and too hard to get the shaver in to do any good. We took her to our vet (the same vet we've used for years), but all she said was "Well, you know she's not a young cat anymore. Maybe you should just euthanize her." That's not going to happen, she's an otherwise healthy cat and probably has a few good years left. (Her mother lived to be almost twenty-one.) Her other suggestion was to possibly give her an anesthesia and try to remove it however possible, whether through shaving, possibly even removing some of her hide, whatever it takes to get it off, but the vet warned us that putting an older cat under anesthesia is very risky and might kill her. So to us that's really not much of an option either.
It seems like it could be such a simple thing to take care of if I just could find out what might dissolve this stuff without hurting her skin. It seems like it's getting more painful for her to walk every day, and I can imagine it would be as it keeps tugging at her hide more and more. I would really appreciate any help or advice someone could give us.
