Has anyone successfully fed these to their cats? I like to feed the Pure Bites treats, but since one of my cats can only have duck for now, and Pure Bites does not offer duck, my options for her are limited. On the chewy.com website, it says that the treats are for dogs AND cats. However, there is a dog picture on the front of the container, and they are clearly labeled for dogs. Also, I don't know where the duck comes from--could be China.
