Question about a Siamese cat age 8

He has been throwing up solid hard food and now only licks the juice out of cans of food i give him three or four cans a day. I’ve been to the vet and they say he’s fine i don’t think so what do you think?

 

Answer from Dr. Gaylord Brown:
If the situation has advanced to just licking the juice from the canned food, then your cat is not fine. This may be hair balls, gastritis, ulcers, or cancer. Get another opinion and get some diagnostic tests done to define the problem.
