Since my cat was just a small kitten, well since she was probably 1 month old (she is now about 2 years old), she has been very aggressive toward everyone. It was really bad when she was younger. She would snap at anybody, including the family, she would run crazily around the house, tear down the curtains, etc., but then we got her spayed and she settled down A LITTLE bit. She doesn't run around as much anymore, but she still likes to attack the other animals when they are playing. In other words, she doesn't like to play and when they want to play, she is mean to them and bites them and hisses at them and stuff. She even picks on the dogs. She only snaps at the family when we pick her up wrong (she has to be held on your shoulder) and only we can pick her up, if ANYONE else tried to pet her, you had better run because she will attack you. She GROWLS out the window at other cats and dogs and even chirps like a bird when she gets really excited. She always tries to get outside because she loves to be outdoors and exploring the front yard, as if it were a big jungle to her. Well, I guess, what I am asking is, has anyone else experienced these kinds of things, and if so, do you have any advice on how to calm her down a little? Thanks!!
