Actually I decided to get it yesterday because I convinced myself that it would be okay for four days :P
The store told me that it was quite likely a male. I took it home and set him up. Having been housed on newspaper previously, he was excited to start digging in the sand. But then he flipped sand into his water bowl and somehow managed to also get a lot of the water out onto the sand, which made the sand clump up :P Maybe I'll switch to corn cob sand...
I also noticed that hognoses move with a snakey version of a penguin waddle when you handle them :P
