hay goes in a small paperboard box - the kind that food items come in (my boys amazingly don't chew it much at all! these boxes last in the cage for a couple months at a time, and usually get pee on them before anything, lol). pellets in two different dishes. chew sticks on different shelves or in a pile on one of their ceramic tiles. lots of hanging toys in their cage, so i don't worry too much about giving many loose toys (toss toys, etc). hay cubes go into a little dish, to keep them from being peed on. treats just get handed straight to the boys.
like others have said, stuff never stays where i put it. most mornings their hay box is knocked off the middle 'floor' and is upside down on the cage bottom, sticks are all over the place, hay cubes are no longer in the dish. i thought about making a more 'secured to the cage bars' hay holder, and finding a way to contain sticks and such, but i honestly think they enjoy making the mess, so i let them have their mess, lol.
