your cat is much more of a threat to your snake than your snake is to it. they should never be allowed to interact--a claw or a bite from the cat would be disasterous for a snake.

my cat unfortunately is insanely interested in all things reptilian. she isn't allowed anywhere close to the snakes when they are out because she would be quick to smack at them. i don't think she really knows what the snake is, but because it moves she wants to catch it and play with it. the snakes don't seem to know that she is a predator and so they wouldn't know to try to get away should attempt this.
