I hate wildlife

So I have a squirrel living in my wall and its really, really annoying. It likes to get up and start squeaking and scratching around 4 am and whenever I am studying in my room. I also sleep with my window open because its super hot at night and we don't have air conditioning or a swamp cooler or anything. This is bad because the birds around my house also like to wake me up really early for no reason, usually around 5 am. And then, the other night I was watching TV and this stray cat just waltzes into my house. I chased it downstairs where it disappeared somewhere, probably into one of my roomates rooms. I looked for it for a while bu couldn't find it so I figured I'd leave it there for a nice surprise. But like I said there, are two many animals running around here. It's time to go hunting!
