Appropriate Punishment?

I had a great start to the Tour de Fleece. I finished spinning 8 ounces of bamboo/merino/silk (most of it was spun prior) and plied it, and began spinning from the fleece I bought a couple weeks ago. I was starting to think "wow, I had forgotten how much I loved spinning!) and I was really excited about actually finishing Tour de Fleece this year... when I came downstairs and found that Chase had eaten my driveband. This is actually the third driveband that she has eaten (with shipping they cost about $20 dollars).

So what should I do with her? My initial thought was that she should have to buy me a new one out of her allowance, but Mike pointed out that she is a cat and does not actually possess or understand currency, so I am out of ideas.
