A plastic file box makes an awesome kitty food storage container.
Sure you can go to the pet store and pay a small fortune for a specifically designed for cat food storage bin. The fancy little flip tops and gadget scoops don't really work that well.
A simple plastic file folder box with a snap on lid, works great! It has the same snap closure on two sides. A little handle if you need to carry it somewhere, but who really does? The handle is good for holding the lid, while your scooping food into the cat dish.
This file folder container holds a 16 pound bag of cat food and it is made by Sterlite.
