This sounds like Fister's behaviour, except that he hardly eats anything or drink. He has also lost a some weight, so I'm worried. He is 16.

I took him to the vet a few weeks ago and he checked him over and could not see anything wrong. He also had the tests for Glucose, Liver, Kidney and the T4, which all came back within a normal level. I got some pills for boosting his appetite and they help a little, but I have to find out out what's wrong, so the next step will probably be an x-ray and possible other tests.

It's so hard seeing our cats age, and not understand what they want to tell us. Fister has had a period of meowing a lot, also. He wants me to be close to him all the time when he's awake, and I do spend a lot of time with him.

Does your grandmother's cat drink enough? If not, she could try to get some water in her with a syringe, like I do with Fister. Also, try to feed her only a little at a time.

Sending lots of positive thoughts.
