I have wondered that.

I used to work in a fileroom and would come home with pockets full of paperclips. One of my cats would stalk the paperclips, tracking them by the jingling sound. He was obsessed with paperclips, and would ceremoniously trot off with them, held in his fangs like defeated prey.

He was stashing them, among other places, at the bottom of his food bowl.

If they're after a metallic taste, keys and coins both taste stronger.

Have you ever actually put a paperclip in your mouth? They're really fun to play with.

:eek:

Both my boys were obsessed with my wax earplugs.

Diz still is - I have to put them in the gourd Secret Santa gave me the other year, otherwise he will carry them off. Although he actually eats them these days - which suggests less klepto and more greed...
