I just want to say that your travails are very funny to read about! That's a clever cat!
The only locking thing I have is a different size of this, which I bought at Walmart in the CD section. Mine has a 3-digit combo lock, not a key, and you can set your own combination.

Turns out the company makes a large line of various locking cases, including makeup cases and such, that may suit your look better.
