We have two cat doors inside our house. One is on the laundry room door. That's so the cats can get in there to do their 'business' without the smell of cat box taking over the house. The other is between the living area and the sleeping area of the house. That door gets closed so we can keep the dogs (and children) in one half of the house or the other, also to save on heating/cooling during sleepy time. The cat door is a necessary there again so the cats can get to their toilet.

Henk and Apple (the grown-up cats) take the doors in a stately fashion, very dignified, very careful. Stitch (the hell spawn kitten) takes them like a panzer division crossing the French border. She'll start by the laundry room and tear ass across the kitchen floor. She'll slowly build up speed as she gains minute amounts of friction on the tiles, much like a cartoon character or dragster. There's a 50/50 chance that she'll make the turn into the dining room otherwise there'll be a loud "thwunk" as she banks off of the oven cabinet. Once she hits carpet the claws come out and she accelerates as if she just turned on the nitrous. The sound of ripping fibers increases until they conclude with a door jarring "THA-WANG" as she dives through the cat door and sends it smacking into the door on its hinges.

The cat doors are pretty good ones and have little switches so they can be set to open both ways, either way alone, or lock closed.

All I can think of every time I hear her assault the door is this.

So far I have resisted my natural urges but I'm unsure how long I can hold out.
