As I mentioned the vet didn't prescribe her anything. I talked to a friend who has been a vet tech for years and he said he hasn't heard of vets prescribing medicine in a case like this. So, it may be that it's not done. I wonder if it has to do with a lack of experience with geriatric cats. Culturally, it's common in this country to let cats roam, so they are likely to die younger. .
