I can personally vouch for this. In Morocco cats were everywhere. Cafes, high rises, farms, University, everywhere I went. Even the airport! As we queued up to the ticket counter (this was decades ago) i saw cats wandering independently. I mused to my companion, "i wonder if they get into the secure area of the airport?" Sure enough, after going through security and waiting at the gate, there goes a feline walking by wholly unbothered. I wondered if cats ever got onto planes unwittingly. Didn't see any on our plane ... still wonder.
