"I have two cats, both of the tabby sort, one of them is going on 10 yrs and the other on 6 years. I have fed them Science Diet from a 20 lb bag since they were very young and they are extremely healthly (as my vet says). Realizing the cost of this food, if you bought another cheap brand, you'd run out faster, the litter box would be a lot fuller (and smellier), and you would eventually pay more than the cost of Science Diet.
Their eyes are bright, their coats beautiful, and I don't mind paying the extra money. I have found that in the long run, it's a bargain in many ways. My cats won't eat anything else!"
