Did your vet test his urine? And, how were his kidney levels by the blood work?
This really does sound like this is kidney disease or possibly diabetes, especially if you've noticed weight loss and decreased appetite. Diabetes may make them hungrier than usual and kidney disease causes the opposite.
Hi Deb
That was in March!!
How is your baby doing as of April 21, 2015??
PLEASE let us know.
Not thyroid according to a test she did. Her advice was to wait and see what happens, but if his behavior continues, bring him back.
Hi Deb,
Just wondering what the vet had to say about your kit.
Could you let us know?
Thanks,
CML
Hello. It sounds like your elderly kitty is suffering from either Hyperthyroid disease, Kidney failure, or both, as HyperT can lead to renal failure. The excessive water intake is a clear sign for both issues. Why he suddenly stopped, I don't know. It's heartbreaking to hear he is thirsty and cries, but isn't drinking. I'm sure it hurts your heart too. It's time to take kitty to the vet. I would do that ASAP.
Please let us know how it goes.
