I have a similar problem with Carmel yowling at night but I can't leave the door open. My akita puppy is shut in the bedroom with me both to keep her away from the cats so there aren't any accidental injuries and protect the rest of the house from destructive puppy teeth, I have slight allergies to cats so I spend all night awake with breathing problems if they sleep on the bed, and to top it off I already have severe insomnia so adding a cat waking me up several times a night is very bad. You don't realize how important sleep is until you don't get any for 5 days. It's actually enough to be declared mentally handicapped.
Wearing the cats out before bed helps and is usually enough for mine. Play with them for awhile preferably with lots of chasing things. Also trying to avoid having them sleep all afternoon or evening is more difficult but very useful. If I let her Carmel will sleep off and on from noon to 9pm and then bounce around the house all night yowling at the door out of boredom but if I toss her a new toy or some catnip in the afternoon or early evening she stays up and instead falls asleep around the time I go to bed. Then she doesn't even notice I'm not around. Final solution when everything else fails is to lock her far enough away I don't hear it while trying to get her enough things to keep her busy. I have a finished basement so I have 1 litterbox, a bed, food, and water down there all the time and when Carmel really won't let me sleep I shut her downstairs with some extra toys or catnip.
