Mixing up a cats diet will actually cause their tummys to become upset, so keep it regular. We feed our kitty dry food, good expensive stuff, not whiskas or anything like that, stuff that is nutritionally balanced. No wet food at all here, I find it's a bit unnecessary for cats, they are fine on just wet. Occasionally as a treat we give her offcuts of chicken, or a small small amount of wet food with dry, if she's sick or whatever, but yea, just dry food for our little princess
