Works great for cat food.
This is great storage for the big (20 lb) bag of cat food. The ants don't get in, the food stays fresher, and it is much easier to store than the original food bag. Having two colors works great for keeping types of cat food separate (adult cat, senior cat, etc.)

As the food is used, the collapsing sides makes it easy to reach the remaining food. Since the food is sealed inside (assuming you close the lid) the cats don't smell the food and try to get inside the bag. Makes life SO much easier not having to deal with the original rip-prone food bag.

Elegant dog food storage solution
Very nicely designed product. Hard to tell the size of it in images without size referents - stands about 18" tall, about 12" across.
Lid is the size of the entire top and large crosshatch design on the surface makes it very easy to open and close. Soft-sided, so it will collapse as it empties. We did not like that aspect, so we simply inserted a large metal popcorn tin as a stiffener.
We're pleased with it, and would not hesitate to buy another one.

Fresh Chow
I bought two of these on a whim since I was tired of looking at huge, open bags of cat and dog food in the pantry. I have found they are wonderful for keeping pet food fresher and keeping the mess down when I have to replenish the food bowls. The large, re-sealable tops close with little effort and really seal in the freshness. Since we had a new puppy that was tearing into the bags, these have been a godsend.
