If the vomit is undigested, I would suspect a dental problem. She may not be able to chew her food properly. I would suggest a dental cleaning and check up and switching to a softer and finer diet that doesn't require as much chewing.
thanks guys
i feed them Nutrience brand. Ive tried other for sensitive stomach etc. I will try smaller portions
Yes, what kind of diet are you feeding your girl?
My cat vomits alot also and we've found if we feed her small meals throught the day, will cut down on the vomitting.
Check diet. Swampy finds that many cats cannot handle certain food textures and types. One of Swampy's cats can't handle the commercial cat treats, for example. Feed him one and up comes dinner.
Also, look at the environment where the cat lives. If you have excessive dust in your house, as an example, the cat can inject it while licking himself, that can cause irritation. Cat litter, too, can cause irritation.
Each cat is different. You just have to experiment. Good luck.
