When Should I Feed My Cat?
When you feed your cat essentially comes down to what works best for their needs. "A variety of feeding styles can maintain good health" in cats, points out the Feline Life Stage Guidelines published the American Association of Feline Practitioners and the American Animal Hospital Association (AAFP-AAHA).

One option is to allow them to eat freestyle with food available 24/7. This method is great if your cat has self-control, but many cats tend to overeat due to anxiety, boredom or health issues. You can also look into automated cat feeders that can regulate how much food your cat eats each day if your cat is prone to overeating.
Breaking up your cat's caloric intake into two or three smaller meals per day works well for most healthy cats, say experts such as Francis Kallfelz, DVM, Ph.D., at the Cornell University College of Veterinary Medicine, as long as they don't have dietary restrictions due to medical issues.
How Do I Choose the Right Cat Food?
When planning your cat's mealtimes, don't just think "how much should I feed my cat?" also consider what goes into the food you're feeding them. Knowing how to read a cat food label helps you decide which food is best for your pet. Make sure to look beyond just the ingredients, and consider the nutrients that they provide. Your cat needs the right balance of protein, fat and carbohydrates. They also require certain vitamins and minerals, like calcium, magnesium and vitamin A.
It's also a good idea to speak with your vet to figure out which type of food is best for your feline friend. Having a clear picture of your cat's health, weight and activity level ensures you choose the food that most benefits your cat's lifestyle.
Is your cat a treat lover? Be sure that treats remain a once-in-a-while delicacy and don't become commonplace. When thinking about how much to feed a cat, calories counts. Approximately 90% of a cat's daily caloric intake should come from well-balanced cat food and 10% (absolute maximum) from treats. If your cat fills up on treats, they're not getting the balanced nutrition they need.
To help your adult cat stay healthy and active, you can use feeding time as enrichment time, too. Some cats eat just because they're bored, so provide them with plenty of opportunities to keep their minds and bodies sharp.
