These little nuggets treats are made out of freeze-dried rabbit. These are very simple, yet very flavorful with rabbit, rabbit liver, rabbit kidney, rabbit heart, and mixed tocopherols (a natural preservative from Vitamin E). Rabbit Nibblets are made in the U.S.A. without any added antibiotics or hormones. What makes the tuna in Only Natural Pet’s canned cat food even more special is that it is pole & line caught. So wild tuna caught by hand for your cat! Carrageenan, the additive that is commonly used in pet food to gel up canned food and is the cause of health problems in many animals, is not found in this food which is a relief to many cat parents. Also, there isn’t any synthetic Vitamin K called Menadione, which is another ingredient in pet food which causes liver issues over time.
