Ok, so I currently have 2 adult DMS (Domestic Shorthair) cats. I feed them dry food and canned food. I usually feed the dry meal in the morning and the canned meal at night. My canned food is usually Felidae or Sheba. (Or something like "Sheba", it has good ingredients though). However, I am rotating dry foods. I feed one bag of Chicken Soup Light, then a bag of Chicken Soup Senior, then a bag of Premium Edge Light, then a bag of Premium Egde Senior. Repeat. But I was wondering if I should add one more brand of high quality dry cat food. So it would be: Chicken Soup Light, Chicken Soup Senior, Premium Edge Light, Premium Edge Senior, (insert brand here) Light, (insert brand here) Senior. I'm not sure what the new brand would be but it would be something similar to Premium Edge & Chicken Soup.

Yay or Nay? Should I add another food or leave it as it is?
