My cats learned very quickly that were not allowed to bat at the snakes in the cage. A spray bottle full of water really works. They do lay on top of the cage, hanging over the edge looking in. The snakes get nose to nose through the wire and never any problems. Even the dog like watching the snakes moving in the cage. I swear, when I first brought the boas home, the cats,all 5, would spend hours watching them through the wire. They (the cats) actually took to sleeping in front of the cage on the floor. I started covering the cage at night to give the snakes some seperation from the other animals. That is as close as they are allowed tho.
I'm right. You're wrong. Get over it.
