My Cat of some 23 years of age has been vomiting for some months now. I had her at the Vets recently, he said she was fine and it was common in old cats. However, she is getting thinner and thinner. She eats, or should I say, laps at the gravy and eats not much solids. I feed her each time she cries, which can be 4 times throughout the night. Any suggestions?
