6 years ago when I moved down here, I found out that the garage had a little kitty door. I decided that this seemed like a brilliant idea to catch myself a pet cat and so I turned the little lock knobby thing to the point where an animal could come in, but couldn't get out.
Of course, after Ivy found us, I left it that way because she and Quazi would frequently go out into the garage and sit at their little kitty window and look outside trying to figure out a way to get out. (What happens if I push on it? hmm, Nothing. Okay...What happens if I push on it now? hunh. Odd. Nothing happened)
Since it's been 6 years and we've never had a problem with animals coming into the garage, I completely forgot about it. Until the other night when we had a feral cat in the garage. Well, we can't blame the cats - they tried to warn us (they both REALLY wanted out in the garage even though it was fuh-reezing outside). It also should have tipped us off as we came home and the garage smelled like cat piss, but I figured that the smell was because I had been cleaning out the litter boxes and throwing the waste in the garbage and we hadn't thrown away any other trash. So instead we sat in the house until the poor animal knocked over a rolled up rug Shawn had next to the garbage can. When we saw the cat, Shawn just opened the garage door and the cat left (though I feel like we should have put food and water out for it first because who knows how long it was stuck in the garage).
But man, can those feral cats jump. It was jumping about 6' straight up in the air trying to get away from us (and it was already in the opposite corner of the garage).
