I got curious, so I went through the snakes currently listed on petfinder (www.petfinder.org). This may or may not accurately reflect overall trends in shelters and other rescues across the country -- dunno. It's just an interesting snapshot!

I did think it was interesting that there's as many albino burms listed as normals, but again I dunno if that means anything or not. Oh, and I didn't separate out the morphs of anything but the burms...and I didn't separate the rat or king species.
