We got Baggy and her brother Samwise (who is very mellow) from our local no kill shelter 7 years ago.  They had a normal upbringing and seemed to get on well.  However, Baggins, the little female who weighs in at 7 pounds, is a real terror.  She growls, she spits, she terrorizes the local mouse, vole, and sparrow populations.  She regularly growls and hisses at her brother trying to whack him all the while.  

She has been known to whack, growl and hiss at the hand that feeds her too. If she gets mad at you look out! You'll lose some skin if you are not careful.  At times she has to be doused with the squirt bottle to get her to stop but, she still will stalk off growling all the while. Then after all the theatrics she will come and make up with you by laying in your lap purring with a few growls mixed in if you don't pet her right.  She's our mean kitty and I've never had a cat like her; pray to God you never will either.
