I took Sherlock for his yearly vaccinations yesterday and mentioned that he was drinking more and noticed he was thinner over last few weeks- he'd lost 300g since this time last year which is a lot for a cat.
Vet said she suspected kidney disease but couldn't get bloods from him as he was so stressed- have another appointment in a couple of weeks for him to be sedated so they can do it then 
his appetite is very good and health otherwise fine so if it is that then hopefully it can be managed
Anyone on here whose cat has this please and can advise? I daren't google as I'm thinking the worst...
