Its hit and miss so to speak whether your bike will arrive safely or not. Use a plastic bike box. Some airlines hire them out (Airfrance did).
I packed my bike in a cardboard bike box, removed all protusions etc and with so much bubble wrap and duct tape that it was silly. It arrived in Argentina (via Aerolineas) as if they had thrown it direct off the cargo bay on to the runway and then an A380 had landed on it. The frame was warped with a huge dent in the down tube rendering it unrideable. Oh.. and it arrived 3 days late. Maybe this says more about Aerolineas than anything else... How your cat has a safe journey.
