How often to feed beef?

Is beef an okay food to have as a major protein in a rotation? Or is it a "sometimes" food? My cats eat all canned food and I always like to find ways to get them a little variety. Beef is about as cheap as chicken, turkey, and duck, but just wanted to see if there was a recommended frequency. Thanks in advance!

I feed beef all the time. I think unless your cats have shown an issue with it there's no problem using it in your regular rotation.
