In the wild, cats seldom share their food unless they have kittens. The best way to alleviate this instinct is to have a never ending supply of food available. This means you need one bowl of food for each cat in the house. No bowl should be allowed to be less than half full and each bowl should be large enough to hold 1-2 cups of food. It is best if the bowls are 8 inches across and about an inch deep to keep the cat whiskers from brushing the sides of the bowl. It is also very important that the bowls be placed in out of the way places. Rooms that you spend time in, like the kitchen, will only encourage your cat to overeat.
Cats are social, if you go to the kitchen to prepare and eat food, then they will hang out with you and if their food is there, they will mimic your behavior even if they are not hungry. It is important to make sure that each bowl is placed in a separate area of the house. When a cat is standing at any one bowl, they should not be able to see another cat at any of the other bowls. There is usually one dominant cat in every group and by spacing the bowls, you prevent him from controlling all the food. You can also rotate food from bowls that empty less frequently to bowls that empty more often. Rotation will maintain food freshness and prevent waste.

They have to assume that you got hit by a bus and they need to eat as much as they can before the other cats in the house figure out that you were in an accident. Once your cats are confident that their food supply is secure they will stop overeating.
