These Friskies Party Mix cat treats are super easy to use. Just open the pack and offer a treat to your cat. It's that simple! When giving these treats to your cat, keep in mind that they're designed to be a supplement to your cat's regular diet, so don't overfeed. Since each treat has less than 2 calories, you can give a few at a time without worry. As for storage, keep the pack in a cool, dry place. Once opened, make sure to seal it tightly to keep the treats fresh. Also, remember that the product is going through a packaging change, so you might get either the new or old one, but the great taste and quality remain the same.
