Hi, hope i didn't post this twice.. My cat is about three years old. We got him from a local shelter when he was about 8 months old. He has always had a problem with hairballs, but has changed over to vomiting. He vomits 2-6 times a day. Everyday. We brought him to the vet, where he was treated for mild dehydration, and given an anti-inflamatory. His calcium level is high, which is being monitored. While under observation, he did not vomit because he would not eat or drink while there. We have elevated his bowl, tried every food available, including the prescription diet from the vet. Nothing has worked. He is now eating Iams dry food. I feed him small amounts 4x a day. He does not eat can food. Although I do continue to offer it to him. Does an elevated calcium level indicate anything else beside cancer? Can a cat live long like this? I don't have a ton of money to try to figure this out. But can I do? He is my best buddy. ALso, can drinking out of the toilet cause this?? I do not use chemicals in the tank, just the bowl, and it is rinsed right away. Why do they do this when they have fresh water??? I am grasping at straws here!! Any one?? Thank you!! Michellle
