My cat has been throwing up for months. She is 10 1/2. I have never had a problem like this before. Sometimes it is hairballs, but most of the time it looks like bile with a tinge of blood in it. I had blood work done recently and everything came back negative. I would appreciate any help to make her feel better. Thank you.
Have you had an x-ray taken? this would be the next step. If worries me that you see blood. I would not wait too long to have an x-ray done. vetcare
