Tubby & Peanut's Mom, that was what I was imagining! Bo is very modest, I don't think I could do that with him (but what a funny visual!)

Nomilynn - I'm glad it was easy for you. Bo really doesn't have any set time to go - just whenever the mood strikes him. I rarely catch my cats in the boxes. That is mainly the reason I took him in for these tests, I caught him in the box twice last week. I didn't know if it was coincidence, or if something is wrong.
