Beautiful cat; really stupid ‘owner’.
Not necessarily. Back when I traveled for NASA I had to always ‘search’ my bag before I closed it because one of our kittens would burrow her way down to the bottom of the bag and hide out.
Otherwise you’d never know she was in there.
I’m sure it can happen; but that cat doesn’t look very tiny and easy to miss. And it seems it would start a ruckus inside at some point before making it to the plane...
