S.,
Do you have any other allergies like hay fever? My adult daughter is not actually allergic to cats if they stay indoors, but if they've been outside, she starts sneezing and her eyes water.If it's a new cat, it may have other stuff on its fur that's causing the problem. But there's a good chance it's the litter! Have you tried Yesterday's News and the other similar products? Good luck!
