I've heard say many times that orange male tabbies are the sweetest and most lovable cats and so far I have found this to be true. My three ginger boys are complete love bugs. They actually compete to be in my lap and at times they all just try to pile in my lap.
My black kitten is just like was said up above... one minute he is full of love and affection and the next minute he is base jumping off the bookcase, knocking over anything that is not nailed down and using the SO and me as his personal climbing posts. My almost senior boy is a solid black as well and he has calmed down for the most part but still seems to find it necessary to cause mischief every once in a while.
My girl is a brown tabby and she has more attitude than a room full 13 year old girls. We call her our little erm... rhymes with witch
She only wants to be pet when its on her terms and if you try to pet her and she wants none of it she gives this sharp meow as if to say "how dare you touch me when I didn't give you permission." She does love my SO though. I think its because he just lets her sit next to him and leaves her alone.
