My snakes aren't Giants, but they are large. They do look very intimidating to nonsnake folk. But they are all tame as kittens and have never bitten. That's were the joke lies.
Somebody brought up that the signs are not good in case there is a fire and the snakes may not get rescued. My come back to that is there is a much greater chance of the house being broken into. And probably by young punks. Maybe the signs will cause the punks to leave the snakes alone.
