I have two Blitz Stack n Stor Storage Bins. They are great for storing pet food. I use one for dog food and the other for cat food. I have had these for a long time and they still look brand new. We have three dogs and nine outside cats. That means a lot of food that has to be stored and these are the perfect way to store it. The bins are made of heavy-duty plastic with a tight fitting door that can be locked, so they can be stored inside or out. If I leave pet food in the original bags, I might have to worry about mice or other pests being drawn to it, but these bins prevent that from happening. This also keeps the food dry and stays fresher longer.
I store these in my utility room closet and they are space saving because one sets on top of the other. They have indentations on the top and little feet on the bottom so they interlock with each other to stay in place. They have a wide opening making it easy to scoop out the contents and easy to clean.
You can get these in 18, 20 & 24 gallon sizes. 18 gal - Measures 16 inches L X 16 inches W X 14 inches H; 20 gal - Measures 18 inches X 17.5 inches X 15 inches; 24 gal - Measures 22 inches X 21 inches X 16 inches. I have the 18 gallon bins and can get about 32 lbs of food in each.
If you need a place to store your pet food, I would highly recommend these.
