My cats love to watch the snake, I have four cats. Kin, my boy, is a scaredy and stays away. Emily and Angel like to sit and watch carefully. Now Carrie, she's a bit of a different story. Carrie bats at the tank. Carrie watches for hours, very intently. Carrie screams at me in the same voice she uses when she wants food. She knows when the snake is out, and SCREAMS at the door to get in. I am convinced she wishes to eat him. I think it's because of how exotic his smell is to her. Now, if he got out, I think they would all run. BUT, it serves as a good reminder to keep his cage locked up tight. Honestly, I think it wouldn't be a problem to introduce a snake and a kitten, but of course don't leave them together unattended. We keep the cats out of Kaa's room now, because I don't want to take any chances.
