Last week, I was mystified by a line of little grey-white balls on my parents' terrace. Ah, they explained, instead of using a shredder to get rid of confidential or vaguely private documents, they tear up the papers, soak them in water, tear them some more, squeeze out the water, mould into balls, and leave to dry. They make very good cat toys, subsequently, they helpfully explained.
Needless to say, I couldn't wait to try ... and then couldn't resist painting them. Maybe they'll be dry by tomorrow, and I can roll them over to the felines?
