The webcomic Two Lumps is based on two cats, Raistlin and the late Caramon. Caramon had a genetic kidney failure that wasn't obvious until a UTI developed; by that time it was too late to save the cat.

Raistlin's human took him to the vet with symptoms of a UTI. Raistlin has the same genetic kidney condition. This time, it was caught earlier.

Raistlin's human is hoping that a course of in-patient treatment will help enough that Raistlin can continue with ongoing outpatient treatment. This is, of course, expensive. If you can do so, contribution would help; if you can't, maybe you can signal-boost.
