I've had 7 Siamese over the past 22 years. I'm down to my last one now.
He's 17 and is an inside cat. (They all died of old age.) If he decided he
wanted out there would be no way in hell I could put up with the howling!

Unless you have a siamese cat. They're worse than nails on a blackboard
and
are quite capable for howling for 200 hours uninterupted.

Hate to say it, but all you can do is make sure to never let such a kitty
taste the outdoors.
