I can't tell you that one sex of cat is better than the other, but I can tell you my experiences. I have had three cats in the past, all males. All three of them are gone. they went outside, and just didn't come back. one, I brought in from the street when I was 8, so as I look back, it's no big surprise that he took off. I now have my first girl kitty, and so far, she doesn't even want to go outside. I have had no trouble with her trying to run away. However, all of my cats (with the possible exception of my street kitty, White Socks) have been the sweetest things ever. This may just be the opinion of a little girl who loved her cats too much to see any bad in them, but I loved them all. Every cat's different, and in my experience, they all make wonderful pets, no matter their gender. I love them all!
