I find it laughable and just factually incorrect that people honestly believe that large constrictors are given up at a higher rate than BPs and other smaller snakes. Go on Craigslist anytime and you will see dozens of BPs and corn/King/milk snakes getting rehomed because their owners were obviously deficient in some way. I rarely see a retic or Burmese Python being given away.
I would even dare to say that large constrictor owners are even MORE responsible when it comes to snake ownership and care. Sure there's the random guy who gets in over his head with a giant snake. But for every one of those there are ten others who buy a bp at an expo and 6 weeks later they are over it.
