If you’re in the habit of leaving kibble in its dish all day, stop right now! That’s the worst thing you can do for your cat’s health and weight. Have specific mealtimes. By leaving the food out all the time, you’re overstimulating the digestive system. Feed adult cats once or twice a day but kittens or pregnant cats need feeding more often. By giving one or two meals only at regular times, your cats will develop a hunger response. Leave the food down for about 30 minutes and then remove it; your cats will learn that they need to eat when you feed them. But don’t let your cats skip more than two meals. If that happens, give them something you know they will eat.
