I am not an advocate of dry food at all. My kittens (12 weeks old) are fed 4 times per day, 3 ounces each of Nutro Max Cat or Natural Choice Kitten canned and they also get a pouch of the Nutro Natural Choice Kitten as a treat once per day.
My adult cats (male is 17 months old - female is 16 months old) are fed 4 times per day, the male receives 3 ounces of Nutro Max Cat Adult formula and the female receives 3 ounces of Nutro Max Cat Adult formula at each feeding. Both also receive a pouch of Nutro Natural Choice Kitten once per day as a treat.
It is my opinion that dry food contributes to unhealthy teeth and gums, hydration problems which result in poor hair coat and urinary tract issues and possibly even future kidney issues. I only feed it to my queen once I put her kittens on solid foods, usually from week 3 in order to help her rebuild her resources after nursing the babies. Once she has regained her tone and condition, I remove it.
By providing your cats with a high-quality, nutritious diet and clean, fresh water (I give my kitties filtered water) at all times, you are making an investment in your cat's future good health and longevity. What you may be putting out monetarily now for a good diet is saved when you go to the vet each year for an annual and you are told your cat is healthy.
