Ive lost a snake to a cat once, the cat was a fatty and took a nap on top of the tank and actually pushed the screening in so there was a gap and the snake disappeared. But that was like ten years ago.

Otherwise I have 4 little dogs, 1 big dog, 3 cats, 2 parrots, 4 budgies and 9 snakes.
I have trouble with one of the cats who wants to eat my budgies but no one notices the snakes.
