I always have dry out and that is a mixture of Royal Canin, Sinsible Choice, Science Diet Nature's Best, Nutro, Max Cat, Eukanuba. I even get these brands when I have a litter of kittens starting to munch on dry food. In the morning I mix 2 5.5 ounce cans of wet food with 2 cups of dry food and everyone one gets that as breakfast. Now you have to remember that it feeds about 15 cats. So they don't get alot. But the dry is out all day. And about 3 - 4 times a year, fix a pot of rice and chicken livers. Whic is a treat for them I use unsalted chicken stock when cooking the rice. I use the water fountains and have have them in several places.
I have been mixing dry food for almost nine years and never had a cat or kitten turn their royal little nose up at it. There is something for all and as for the kittens they become use to the mixture and the new parents can use all or some or just one if they want and it will not upset their tummies. I do send kitten packs with all new parents of the foods I feed them. So far never had one say the kitten had tummy problems from switching the food or not using one or more of them.
