Feeding your cat this Purina Pro Plan canned food is easy. Just open the can and serve it directly to your cat. You can leave it in the bowl for a few hours, but if it's warm outside, remove any uneaten food after 30 minutes to keep it fresh. Make sure to provide plenty of clean water for your cat to drink. This food is suitable for adult cats only, so don't feed it to kittens. Store the unopened cans in a cool, dry place. Once opened, keep the can covered in the fridge and use within 2 - 3 days.
