As for the driving the snake around thing - it works! But you have to drive around in a neighborhood with a lot of restauraunts.
When my snakes see a Ruby Tuesdays, or an Applebees, or even a Wendys drive-through, they just can't wait to eat.
If I drive them around a residential neighborhood, they only want to mow the lawn and watch TV.
So remember, if you are trying to stimulate a feeding response, drive by a restaurant. Don't drive by a Dunkin' Donuts or anything like that. Junk food is bad for snakes.
