Gee, what a hard one…. everyone’s buns are so different. My Henry actually chose his toilet and we happily went with the flow. Then when we decided to build him a house (cause I wanted it to look nicer and blend into my kitchen/dining room) I bought a cabinet with doors on the front (I thought great – easy access for toilet cleaning & I called it his ensuite) cut a hole/doorway in the side to sit next to his cage which is open. Bugger me!!!! He then chose to have his toilet at the other end of his area. No probs – just a bit harder to get in to clean. And his old ensuite in the cabinet is just a way out for him through the night – yes he worked out how to open those dam front doors!
Again, different to most BBer’s, I use shredded paper and newspaper in his toilet (change it daily) and the one time I gave him a fleece blanket he wee’d all over it and chewed it. Now I only line his cage with newspaper and catalogues. And I keep his hay available in a cat litter tray. He lays in it after a graze, and he doesn’t wee or poop in it.
My comforter/bed – yes, that was his second toilet till I had him neutered. Thank fully I’ve had no probs with Henry since then. Not sure if this helped, but just to let you know how different everyone and every bun can be…. all the best, Henry’s mum.
