One QLer Molten Metal has been very helpful in such situations and has been helping out over six years now. I am not sure if any of Molten's assurances of finding lost animals, wallets, gold rings, usb's or lost love hold true, but let's wait and see a response coming from this person. Molten usually asks for 3 days to fix things up.
Best of luck in finding your lost cat and hope it returns home soon.
