*AWE* Hank is a handsome kitty. Good luck in your decision about getting a 2nd kitty.
We had 1, 1 year old Kitty, Horatio & we recently adopted our 1 year old Siamese Mix girl Yuki & they are inseperable! They LOVE to play, cuddle, clean eachother, etc! It ended up to be the best decision ever! Instead of Horatio sleeping all day, They are playing together all the time. It was a wonderful decision to get a 2nd kitty, but she wasn't a kitten, she is either a year old or "just" under a year. So she is close in age to him. I liked the idea of that better.
