Wayne, you could try to feed Tiger some lite canned food and mix in some dry food with it so you don't have to feed her so much wet food. When I was growing up we had a cat named Smokey who had a sensitive stomach and my Mom would mix his food like this and he had no problems after that. You could also try some of the dry foods that they make for sensitive stomachs. All cats will throw up occasionally and that is quite normal. Tough Cookie, you should start feeding your cats a lite formula dry cat food and limit the amount of food that you give them. I used to feed my cats wet food mixed with dry but now I only feed them dry food. Storm had to have his teeth cleaned and it's also better for them in the long run. Good luck.
