LOL, if they are big enough to wrap around the whole clutch of pea eggs, you need one of @zazouse 's dogs!
I'd be buying a whole bunch of hardware cloth and looking for holes...
Baby snakes are more pea snack-sized
Maybe because they eat snakes? And bugs and spiders?
And then there's the ornamental aspect!
I have always thought the snake aspect alone would make it worth keeping them, and that's often quoted as the reason zoos have them, at least out here....
