Using this cat food is super easy. Just open the single - serve pack and serve it to your cat. You don't need to worry about leftovers, but if your cat doesn't finish the whole serving at once, you can store the remaining food in the fridge for a short time. Remember to bring it to room temperature before serving it again, as cats usually prefer food at a warmer temperature. There's no special maintenance needed for the product itself. Just keep the unopened packs in a cool, dry place away from direct sunlight. Enjoy seeing your cat relish this fresh and yummy meal every time!
