i am getting a kitten from a friend. i already have a kitty that my roommate found in an alley. she is about 1 year old and is very sweet but very violent when she feels threatened due to her life in da hood (i took my girlfriend's cat over to meet her and it was not good).She is attached to me like crazy and just follows me around the house. i am worried she will not like shared attention especially since a kitten would bother her all the time. i really am scared she will hurt the new kitten. how can they be friends? will i just have to wait until it can defend itself and they become friends from being equals? (i witnessed this from seeing it happen when my parent's cat had to deal with a new boston terrierin the family) would it make a difference if they were both girls or should i get a male kitten?
