Arch Nemesis or My Replacement

I’m having a standoff. With a cat. It started yesterday. It started raining, so I went around my house partially closing the windows to make sure the rain didn’t come in more than was absolutely necessary. This is a tricky maneuver because if the wind blows the right (or should I say wrong?) way, it gets in regardless of what I do. This is, of course, thanks to the fact that my landlord never got around to putting new glass in the broken, and in some cases nonexistent, panes. I did what anyone would do—used cardboard and duct tape to patch them myself. It’s generally effective, but after living in my house for a year and a half, some water is inevitable. Anyway, so I shut the window in my room last, and made eye contact with this mangy looking white cat sitting outside. I registered the look it gave me immediately. The look was that that a teenager gives his parents when they’re about to leave him/her in charge of the house for the weekend. It says, "Of course I won’t have a party", but you know that is exactly what he/she is planning. The look the cat gave me said, “Of course I wouldn’t dream of going through the window into your house—when you’re home.” I hate this cat. This morning I saw it again sitting on a table that I abandoned on my front porch about a year ago in hopes that someone would steal it. I noticed the cat’s ear, which was completely black and looked nearly rotten. But, rather than feel sorry for said cat, I just saw the look in his eyes and knew that he was just waiting for me to move out in a few weeks so he can claim my house for himself. Adding insult to injury, he is completely white. The only reason I mention this is that last October, shortly after moving into my house, I came home to find 3 totally white baby kittens stashed behind my refrigerator. It was disgusting. But not nearly as disgusting as knowing that the next tenant to my lovely home will be this disgusting creature that has already probably been in my house, wreaking havoc but finally catching the lone mouse that keeps scurrying around my kitchen.
