Thanks for those links. Those guidelines sound very similar to the
ones given to her by the airline she will be flyinig with.

The carriers we looked at were IATA approved but the pet shop only had
one brand so she will be looking further. I just thought the grill in
the top was general a bad idea!

Has your friend asked the airline if the cat can fly in the plane with her?
Ive heard about so many stories of pets flying in the hold..
