To feed your adult cat, simply measure out the appropriate amount of Petcurean Summit Range Rotisserie dry cat food according to your cat's age, weight, and activity level. You can put it in a clean food bowl and leave it out for your cat to eat throughout the day. Make sure your cat always has access to fresh water. Keep the cat food in a cool, dry place and seal the bag tightly after each use to maintain its freshness. If your cat has any special dietary needs or health issues, it's a good idea to consult your vet before starting this food.
