I wouldn't go around telling too many pt'ers than rabbits, rats, and birds aren't 'pets' and don't deserve to live just as much as a kitten does.

I would also like to point out that reptile keepers have been plagued by rumors of this sort of thing happening "all the time!" Does anyone have any proof that the craigslist guy isn't just some troll trying to stir up animal lovers by bringing up an urban legend AGAIN? In my experience, the emails I get about things like this tend to kind of fizzle out into totally unverifiable internet rumor after a bit of investigation. I am not saying it has never happened, just that it isn't fair or realistic to think every free kitten ad will be read by a snake-mommy like me who will instantly begin rubbing her hands greedily at the thought of saving a whole 75 cents or so on a frozen rat.
