Hi, I am Dr. Peter and would like to help.

2. He has been losing weight over the past several years a lb or two a year His original weight was 17 lbs.

3 His appetite is the same


Expert:  Dr. Peter replied 7 years ago.

When a cat starts drinking more then normal, it is usually a sign of either kidney disease, diabetes, infections, cancer, etc. The excess amount of water is what causes the vomiting, now, there is an underlying illness causing him to drink more. You need to have him checked by your vet and have a blood test done to rule in or rule out any of the above conditions. All of these conditions are treatable, the earlier we get to them the better the prognosis. Consider an appointment with your day vet soon.
