My daughter had a bucket of crayons, pencils, etc on the living room floor while Shadow was out. She wasn't paying attention, but she showed me a tip eraser with a small piece missing from it and told me that she thought Shadow ate it. When I went into the room to look for the piece Shadow had a crayon that she was munching on. She got a bit of the paper wrapper from the crayon and possibly a few shavings of crayon wax. We couldn't find the missing piece of eraser, either, so I think Shadow may have eaten that too. The eraser piece was less than 1/2 centimeter around, but still. Has anyone else had their bun eat these kinds of things? Is there anything I should do for her, or is it just a matter of waiting it out and watching her?
