When was the last time you saw a cat grazing in a wheat field? Never, because cats are carnivores. Check out those teeth! So, we used real fish or poultry as the first ingredient in our Grain Free Cat Treats. We didn't use grains and fillers, like many other cat treats. And best yet? Redbarn Cat Treats are Grain Free, for less risk of food allergies. Shelf Life: 36 months (Store in a cool dry place. Reseal after use.) Supervision is recommended when giving your dog any treat. Always provide plenty of fresh water. Wash your hands after handling pet food or pet treats or touching an animal, animal feed, or animal waste.
