I want to know the same thing, Lovelyloribeth. I've been stuffing toilet roll middles with paper and card with a few treats tucked inside. Now I've read there's a problem with the glue and we shouldn't give them to our birds. How about cereal boxes? I save the shreddings from the day before and use them again to stuff into cardboard rolls or I've also folded a piece of card, made a couple of holes in the ends and tied with a short piece of twine, and stuffed that. I bought corn leaf chews sold for small animals and Gwynn likes shredding those and the debris is still re-usable for another go or two. I tried stuffing sheddable bits and dried fruit into a plastic toy. He loved it, spent ages pulling it all out then set about dismantling the toy. I wrap his apple pieces in screws of paper and pile them into a container. I saw a great idea for using a plastic bottle, making holes to push straws through, so the straws have to be pulled out to let the treat fall down to where it can be reached. There are other threads on the subject so I'm off for another read.
