Thanks for all your suggestions, Lara. I knew I could count on some good info from you.

I have tried the things you mention... giving him wet food (the Whiskas pouches with 12 in box) with a little extra boiled water in. Since it's hot water, he can smell it better and will lick up the juice, and sometimes even eat a little of the meat. It's difficult to tell which flavour he wants, though. Some days he will eat the meat ones and some days the fish ones. He will not eat the rest of a pouch if it has been open, so I try to sit with it under his nose to make him eat/drink more. I do that with his glass of water, also. Sometimes it works and sometimes not.

The syringe I have also tried, but he hates that, so it's difficult. Half of it will run down his cheek. I have used two different sizes syringes.

The vet said he was not dehydrated, so that's good. He told me that you can normally tell if they are dehydrated by looking at their gums. I do think his gums are a little pale, though.

After breakfast, he will come out when he sees his brush, so that's also good.

These two past days, he has gone to the bathroom to lick up some water from the floor. When I see him go out there, I rush out to turn the tap on. A few times I have seen drink from the Pet Mate, also, but very little.

Somehow, I have a feeling that he wants to eat, but finds it difficult to swallow. I'm not quite sure. Will take him for a check again, unless he gets better. I suppose an X-ray might be in order.
