Oh yeah, they have their little quirks, and personalities.
My boy Tyson has one that I laugh at all the time. Last winter I added a second water bowl to boost humidity. It's a simple square, plastic dog bowl that's hollowed out underneath. You can get them at Wal-Mart for about a dollar. Well, I placed it on top of his RBI hide, thinking it would basically be ignored but help with humidity. Nope! Tyson likes to "hide" under it, though he doesn't even almost fit. He ends up lifting the hide up, so that at least half of his body is exposed, but his head is usually hidden (unless he's getting hungry) so he thinks he's hiding. Often times his body is draped over the side of the RBI hide basically falling off. It's too funny. I've tried to snap photos, but the glass always creates a glare and crappy pics.
