Annoying Neighbor Cat

About a week ago I started hearing very disturbing noises coming from outside. (The heat is on full-blast in  my apartment, so at least one window is always open.) At first it really upset me, thinking that someone was hurting a cat, but then my friend Heidi told me that cats in heat often make horrible noises.

I heard the cat cries again today, looked down from my window and there was the cuprit. I've had plenty of annoying neighbors before, but none of them were cats! I guess there is a first time for everything.
