Mice Or Chipmunks?

We have mice or chipmunks. They live in our "Lazy Susan" and they're eating our food. I mad because they eat all the good stuff. Such as CocoChia, rice cakes, chips, and cheese stuffed pretzels! All the stuff I love...all gone in the trash. My poor rice cakes!

We think that they live in the hole above, but we're not certain. There is no other hole and we've never seen mice (or chipmunks) running around so that's our only conclusion. So if you have any tips on how to get rid of these guys *with out* toxins please comment!
