Some breeders seem to sell adult rabbits at cheap prices, and then some psychopaths buy them under the pretense of keeping them as pets & then illegally live-feed them to their large reptile pets (large snakes or monitor lizards).
e.g. https://sfbay.craigslist.org/sby/for/d/san-jose-adult-holland-lop-bunny-rabbits/7905730672.html
Even saw one for $20.
