Ideally, your cat’s diet should consist of high-quality cat food. However, if you are out of cat food, there are a few options until you run out to get some more. Lean, cooked meat with no added flavors or ingredients, such as chicken and lean beef as well as fish are options. Try to avoid canned tuna in large quantities. And if you find yourself often out of food, consider a cat feeder, which may help you keep better track, and also allow your cat proper mealtimes if you’re out of your house or apartment often.
