OH YES!!!! I had a foster this past year that was quite the hellion!!! She had babies when she came in and after they were gone and she was spayed, she beat the snot out of every cat here! She was great to me, but what a stinker to any other living creature! Her name was Millie, which started as Miss Millie and ended as Mean Millie! I couldn't get her adopted out quickly enough! The level of tension quickly decreased once she was gone! LOL!

Here she is stalking and smacking!
