Cat's Eyes Have Tears While Eating

Hi, everybody.

I'm new around here and I have this problem that I don't really know what to think of it. I have 4 cats, all rescued and all in excellent health. But Smokey, a 1 year old Russian Blue mixed (or so they told me) has tears in his eyes every time he eats. Now here's the funny part: He doesn't care much at all about food and sometimes he goes for weeks eating just the bare minimum. Our vet doesn't seem to be concerned, but I am. I have left Smokey without food for about 12 hours and he still doesn't care for the food and ever rejects it after being 12 hours without eating. This doesn't seem to be the behavior of a healthy cat? And sure enough, each time he eats, there are tears. The tears literally fall down on his food, ever since he was a little tiny kitten. I was wondering what kind of exams I should ask the vet? She doesn't seem to be concerned at all about this and this alone is cause of great concern to me. Any inputs are very much appreciated.

Could you post pictures? Does he have runny eyes or nose any other times?

I am wondering the same thing... does the cat have watery eyes other than just during mealtime? That would be good to know. I have a cat with one watery eye. But she has an Herpetic eye from the Herpes virus. Her eye runs like that when she eats too. BUT her eye is watery throughout the day. It is much more so when she eats. You say it is both eyes? If you are really concerned and not feeling satisfied with your vet's answers, then I would get a second opinion. The poor appetite is worrisome and should be addressed. Is she underweight?
