We've now figured out the mice had been feeding on my homemade rice bean bags from Zech's 4th birthday party. I guess I should have been storing them in a better location... instead of a playroom, in a basement. They ate through every single bag I had. Note to self, don’t store rice in beanbags, choose airtight containers.
And here's the funny part, you know you’ve been catching too many mice when your four year old son gets mad at the laptop and yells, "Could you hand me that mouse trap, PLEASE!?!"
