I read about the Fence Lizard before and thought that was a pretty neat trick, and wondered why they haven't synthesized that protein yet?
I like your idea except the exterminating part... : (
My cats must be slacking! I've 2 cats and there's still a menagerie of lizards, frogs, birds, and snakes. There was even a skink(legless lizard)in my bathroom! And I live in a regular neighborhood, not a swamp.
Here's some hatched out lizard eggs I found in a candleholder last week on my back porch.
Maybe I should start trying to raise some Western Fence Lizards? Better than sucking on a lizard!
