Rick,
That is a very nice box! How cool of your wife to make that for you. Also, wow, your daughter could get hurt lifting that big boy of fur. I think it looks very practical and your right that it is about the size of a large Cliff’s box.
Out of curiosity 1)explain the use of the mesh on the bottom half of each side; do you put your hook into the mesh? 2)Is the foam insert grooved or did you “cut” linear lines in it like a Cliff’s box for your hook points? 3)Is that a Pogo stick in the background?
Addendum: on closer inspection, those are obviously crutches!
