SK has the right of it - Some of your cats symptoms will most likely be the same as renal failure if they are undersized and can't filter as much as a regular kidney

Thankfully, he's not at the stage where his kidneys are failing. They're smaller than they should be, but that's it for now. He's now stopped eating the dry cat food you buy from supermarkets because they ALL actually cause cat kidneys to shrink. So he's now on the fancy, expensive sort you can only buy from vets and pet supply places. They actually help the kidneys.

Ohh, no no no...Yea, this is why we should talk - Sent you a PM
