My vet says dry food only. Is wet food bad for cat teeth or kidneys?

Pet's info: Cat | Domestic Shorthair | Male | neutered | 15 lbs

I have two neutered kitties. My vet insists that wet food will rot their teeth, and to feed only dry. I hear that that isn't good for their kidneys. He wanted to give them an appetite stimulant so that they HAVE to eat the dry food only. They are 2 and 4 years old, and I have their teeth cleaned yearly. Why can't I mix a little good wet food in to make it more palatable? The wet has water, and let's face it...less calories. They are a little chubby, and most cats don't really chew the kibble.

There are many different opinions about pet food, even in the veterinary community. I think it is fine to offer canned and dry food to cats. Most people will leave dry food out and will offer the canned food once to twice a day but don’t leave that out as it will spoil. If the cats are heavy, look for low-calorie foods. Dry food isn’t that good for the teeth unless it is a special dental formula. These formulas have kibble that will not break until the tooth is fully engaged into the kibble. Otherwise kibble only helps to keep the tips of the teeth clean and not the gumline. Kibble is however not bad for the kidneys. Canned food is better for the kidneys because of the water content but if kidney disease does develop, cats will need a special diet for kidney disease. I hope this helps and please feel free to post any additional questions about Moe and Mac.
