Since the weather warmed up, our common backyard has more than the usual crowds of birds coming to nest. so Bootie, the shorter, fatter, naughtier ruffian is ready at any time, given the opportunity, to catch a bird...or the squirrel that loves to tease both cats by running up and down the adjacent house wall and stopping mid ladder to stare right at them as they sit , faces squashed against the screens. (I've seen it, its like who blinks first) As the weather warms, there are bits of fluff and flotsam that whiz by and so the fat meatballee has learned to smack the nylon screen. I was in the living room and kept hearing thump....thump, and walk into bedroom to find him whacking the screen so hard I was afriad one really good whack would send him 2 floors down and he would be off chasing everything. When the doorbell rings and he runs to answer, (no matter how many times I ask if its really for him), he's got faith that one day some of his buddies from the shelter will come by so he can show off. So I bought large metal window screens to place in front of the screens where they sit every day and watch the world and whack at odd bits. I put the screens in place last night, and you would have thought I cut their lines of communication. ALtho I could see thru, the new screen made it dark and dense to really have any fun, you cannt reach flotsam with a metal screen in front of your face. Both of them refused to go near the windows. Mr. Boo was skulking and sulking most of the evening. When he's upset, he paces back and forth. He is too funny. If he could actually talk, I'd have a 24/7 headache, being confined to body language, he does very well for himself. This morning I found both of them sitting glumly, Bootie on a chair and Mr. Boo was rolling on his back on the bed staring at the ceiling. Normally they watch the sunrise evvery morning and wait for the first birds. I caved and removed the screens and immediately both took their places at a window.
