We talked about this years ago here. The idea of putting a little camera on your cat to see where the heck he goes when he goes out at night. These folks have gone and done that! And it was all sciency and what not.
4 of the 60 cats were found to be entering the houses of 2nd owners! I’m sure if I could have seen half the stuff that McGonnigle did, I’d have died. He climbed aluminum ladders to get on roofs; he got into my refrigerator and calmly walked OUT when I opened it. He had no fear. Even when he was treed by a HUGE dog, he calculated when the dog was far enough away from the tree (not far) and he came down and hopped a fence JUST in time. No rush. No big deal.
