cat trick
we used to have a kitty door so katz could go in and out whenever she wanted. then a local raccoon discovered it could come in and eat katz's cat food whenever it wanted. so the kitty door went. now we have to let katz out whenever she wants. i trained her that the sliding door opens suddenly and closes quickly. and if she doesn't instantly zoom through that door at light speed it'll squish her. so one day the sliding screen door was shut. when katz's whiskers touched that screen door her front end came to an absolute and abrupt halt. the ass end of the cat continued moving forward until the cat was 3 cms thick and looked like a fuzzy black pancake. then katz went all terminator 2. the front end of the cat suddenly appeared where the back end of the cat was a split second ago. and katz took off in the opposite direction at light speed before the door could squish her. now katz finds someone else to open her door.
