In general my boas are much neater than my retics. My boas tend to go in one corner, then they sit in the opposite corner and look at you like... "Oh slave, come clean that up NOW". The retics go in multiple spots and then crawl through it - repeatedly.
Oh and for even more fun my SD retic male has picked up an annoying habit. He will pee on the floor the instant he comes out of his enclosure. The first time I thought it was an accident, then he did it again the next time and I thought it was coincidence. Nope. Every. Single. Time. I have to drop his back third into a large tub with a towel in it to catch the mess.
