I also mix in cottage cheese, but I use 1% or 2% fat (so us humans can eat it too!) I also mix in plain yogurt, and several different varieties of meat-based Gerber baby food too. Molly especially likes the apples & chicken (what a combo..yuck!) formula. My mom's adult boxer boys get mashed up sweet potatoes mixed in with their kibble and they like that. Anything to keep meal time interesting, I guess!
