she must have made quite a lot from property dev as it's very expensive to fly kitty in to the UK from Spain - bit less so the other way. They used not to have to go as 'cargo' but could go as 'excess baggage' to and from England, which is much quicker for the cat but is still the hold. I think that's pretty stressful but it does sound like her cat's used to it. Much less stressful is taking them in with you, but BA etc don't allow that. I could rant, but I won't! Kitty may prefer it to hours in the car. Some cats do travel well. Others, like my friend's cat, doesn't even like 2 mins down to the vet!
