You can give it as a standalone meal or mix it with dry kitten food for a different texture. This food is designed for kittens under one year old, pregnant, or nursing cats, so make sure your cat fits this description before feeding. Don't feed it to adult cats, cats aged 7 and above, or obese cats. Store the unopened pouch in a cool, dry place. Once opened, refrigerate any leftovers and use them within a day to keep the food fresh and safe for your kitten.
