First day...cat went in to eat more than once, and the trip plate didn't work. Got that figured out...day 2, it poured all night. Day 3...I caught one! She escaped while I was carrying the trap to the car. I don't know how she did it! It was reaaally hard to pick that thing up because it was unbalanced with her weight, but she leaped suddenly at the door and somehow got it open (the trap door..the rear was secure). {{{sigh}}} Is it the trap, or does this happen?
