Siamese kitten with runny eyes

Mama kitty had a litter of 6 healthy kittens. When they started opening their eyes, one of them couldn't because it had "sleepy" sealing it. I called the vet, and he said bathe it with a warm wet rag. Now the kittens are 8 weeks old, and I have 2 babies left (that weren't adopted), and that is because their eyes water, and are red...typical sinus allergy reactions. The vet told me to get Murine, and that helps some, but they still water. I have never experienced this before in kittens, but their grandma always squinted her eyes. I smoke, so I am thinking they are allergic to that, as well as dust, and who knows what else. Has anyone every successfully eliminated this problem?

Sounds like an allergy. As the cats start to grow and mature, if it is an allergy, they might outgrow it. My cat has allergies. His nose used to constantly run, but it's an off again, on again thing now. Mostly off. It's been this way for his entire lifetime and he'll be 16 years old on June 13th.
