Cat Urinating Excessively and NOT Eating

Hi -

I have an 11 year old cat. He has a history of occasionally urinating on the carpet, etc. He also had high ALT levels a few years ago and severely diminished appetite and vets said he likely wouldn't live long. Much to everyone's surprise, he eventually got his appetite back and the ALT level came back to normal.

About five months ago, he started to drink and urinate more. Slowly, his appetite decreased. Two months ago, I brought him to the vet. He checked him out including an x-ray and bloodwork. The x-ray looked fine and all of the bloodwork/urinalysis was fine. His glucose was 140 so within normal range but perhaps not optimum? We gave him Clavamox which had no affect.

Since then, the increased drinking and urinating has continued to where he is now going about eight times a day, drinking and hanging around the water bowl at times. He went from 14.1 lbs to 12.13 lbs in that two months. Over the past week, his appetite is almost completely gone and today he is just not eating ANYTHING. The vet wants to recheck his glucose and possibly do an ultrasound. Any thoughts?

Thanks very much.

Welcome to this forum!

That is very concerning. I would add full bloodwork to your list. And, I think you should take him to the Vet's first thing in the morning!

I'd also suggest that you try to get some food into him - cats that are not eating are prone to developing another serious condition. In situations like this, feeding first stage meat baby food via syringe (being very careful that the cat does not aspirate the food) is often recommended.

I've seen your request "elsewhere"...please, do not expect that you will find the answer on forums...the longer you delay in obtaining proper Veterinary care for your cat, the greater the danger.

I would strongly suggest you ask the vet to check renal function - even if it was normal last time, it is possible this is related to chronic renal failure - the red flags for me were:
increased thirst and increased urination, decreased appetite, loss of weight. I know this can fit other issues, but I'd doublecheck to rule out renal issues.
