Best of luck with yours! Mine have been inconsistent.
For a short time during her childhood, Satin used her litter box on her own. I did the thing where I used to move every single poop to her litter box. Fortunately, she got the idea. Then, one day, she started using her wheel exclusively. To this day, she's a wheel pooper. She won't poop unless she's moving.
Tex is... uh... Tex. He used to use a litter box to pee, but pointed his little rump at the walls and made poop murals. Now, mostly he uses his wheel and then tracks it EVERYWHERE. And I find logs willy-nilly. While messy, I think I prefer it to the poop murals *sigh*
Oh hedgies... gotta love 'em.
