Best food storage for dog or cat food

I purchased these several months ago, maybe even a year... All I can say is that they are the best purchase I ever made :)

What I love about them
They are on wheels
They have an attached lid
They are semi-clear (view food levels)
The lid locks
Sturdy
Affordable
Food is kept moist

What I don't like
The only place that I know sells them is the container store. Miles from my house

Overall, if you have pets, you should have these !!
