My 15 year old male cat seems to be drinking more water recently and he seems to urinate more although he is not going to the litter box anymore than normal. His appetite is great he is frisky and his weight is steady. I have switched his cat food recently he was eating Iams senior for the last 5 years but then he got where he just didn't like it. My concern is what is considered excessive drinking and urination for cats

Hmm... I really dont know. Sorry. The cat food prolly has something to do with it. I would just call the vet and ask them. Then if they say its needed, bring your kitty in.

I agree with the other poster that the food likely has something to do with the increase in drinking and/or urine volume.
As far as excessive drinking...I have a book that says that cats fed commercial dry food will consume 1.5 - 2ml of water per gram of dry food eaten but will need to consume much less if fed canned food only. It also says that the water requirement for cats in ml per day is roughly equivelent to its calorie requirements. So if your cat is consuming 200 kcal per day then it should be drinking about 200ml of water per day. The amount of water consumed,the amount of fiber & fat in the diet and the activity level of the cat would have an effect on the urine volume and/or frequency. Hope this helps.
