Cages considered as approved by IATA (the International Air Transport Association) are the only ones permitted for animal travel.
To ensure the cage is IATA-approved, it needs to be:
- closed at the front (grill) with a centralised lock
- sturdy (the upper and lower part locked with screws and not with clips, with a steel door and a hard plastic shell)
- secure (good air flow, secure door locking, wheels are not recommended)
If you would like to obtain a travel cage, it would be best to get some advice. In fact, although many pet shops and websites offer IATA-approved travel cages, they are often not suitable for air freight travel.
