There is a thief in my midst

My cat stole my stamps.  She climbed on top of the fridge to unhook the stamps and steal them away.  Then I stood around and called her a thieving whore for 10 minutes while I couldn't find my stamps.  It made me feel better.  I have since found the stamps as she is not a good thief and got them stuck to a cabinet next to the fridge.  Oh help me if she ever actually becomes stealthy.
