I've been using freeze-dried chicken breast, beef, and bison as cat treats. I don't add anything to them at all. I freeze-dry all the treats myself. However, I'm looking for a bit of a change of pace for my kitties. I was thinking of using some cooked beef, basting it with vegetable oil, and then sprinkling some chicory root, sea salt, garlic, and a multi-vitamin/mineral powder on it. I was going to do the same with chicken, but maybe not use the vitamin supplement on the chicken. What do you think?
