Cats with a wide range of health problems will improve by feeding them wet food. Simply put, "the cheapest wet food is better than the most expensive dry food."

Junkyard Cat's story:
We found him at a junkyard when he was a few months old and brought him home. After about two months of bringing the kitten home he was having problems: peeing outside the box, licking his genitals and crying. We took him to the vet and they diagnosed a urinary infection. They gave him medication, but it did not clear up the problem. (I have heard of some very invasive treatment for this condition.) Luckily, someone told me about the wet food vs. dry food. This was a life-saver for us and especially our kitty. I wanted to get the word out.
