My cat Mia, a 6lb. ~1 year old, is the most annoying animal I've ever owned. She enjoys yowling at the front door of my apartment while my girlfriend and I sleep, forcing us to get up and let her out. She'll then yowl at the front door from the other side until we let her in. Other silly cat games include: Running from you when you open the door to let her in and hiding under my car until you close the door, then yowling to get you to come back to the door, sitting in the corner of my bedroom on my old guitar amp and yowling. Yowling *while* being petted. Yowling at you while you're in the shower, as she watches you bathe. Yowl, yowl, yowl. She's a great cat beyond the constant talk, fun to play with and cute as a button. She is not yet fixed, but is not exhibiting any signs of heat that I can tell. She is going to the vet for the spaying this coming weekend, but I'm wondering if it's really going to make any difference. This seems like a personality thing.
