I wouldn't worry about it too much,Hun. As long as the things you have in his cage arecompletely natural (nothing with any sort of finishing on it, oranything other than paper or wood products), he's fine eatingthem. I even give my buns those soft paper drink holders youget from places like McDonald's because I can tell they're recycledpaper, and have no dyes in them! They can also have cardboardboxes (as long as they don't have any shiny printings on the outside,they should just be cardboard). He can even have newspaper,as it's made with vegetable dye!
He's just getting fiber from all different kinds of sources, andenjoying the bounty of different flavors you've given him.It's fun for buns!
As long as he's eating plenty of hay and the right amount of pellets, he's just fine, don't worry!
