I currently have a 2.5 year old Tortoiseshell Colored cat. She is a female and very temperamental. I want to get a male kitten - I am looking at a Tabby. Do you think this is not going to go over well? I have done research on Tortoiseshell cats and although they can be naughty I've read they are very maternal. So I am hoping they will get along. What do you think?
