It's nothing more than a picture of the cornsnake responding to the cat in what I thought was a funny way. Every animal we have from the dogs, the cat, the snakes or the kids are all safe and protected from any dangerous interactions with each other. Sometimes a funny picture is just that.
We're just trying to help. There is simply ZERO benefit to those to animals being face-to-face. It stresses the snake and isn't fair.
....and you didn't answer the question about the lid being secured. Are there clips or locks on it?
