Door open. My kitty sleeps in bed with me and she likes to come and go in the night, she'd wake me up if the door was closed!

Closed because many years ago a firefighter gave a fire safety talk at our elementary school. He told us to keep the door closed at night since it can give you an extra 30 minutes to escape in a fire. For some reason this advice stuck with me...

Closed, got to keep separation from the pets so I can sleep peacefully. Don't need a cat purrkoring off my face at 3 am.

Open, because cat

Open, to let my stupid cat out otherwise he cries.

(I love him)

Closed. Open is a fire hazard.

Closed. Even a simple hollow core door can offer 30 minutes or more of protection from smoke and indirect fire. More time for alarms to go off and get to safety.

Closed. If there's a fire in the other parts of your house, you'll have more time to be alerted and escape.

Closed. Damn cat. She's not looking to snuggle into bed. She wants to wake you up. Why? Who knows.

open so cats can walk freely

Open, so that the air that gets pumped into my room can tell the Mr. Thermostat in the hall that it's actually fine in there and they don't need to call Mr. Furnace or Mrs. A/C.

Closed for AC, but open a crack to let the clingy cat in and out and in and out and in and out and in and out.

Open. I have dogs and cats. I wouldn't get a second of sleep if i locked either dogs or cats out of the bedroom

CLOSE YOUR DOORS. Closed doors give you a much better chance of survival if your house catches on fire.

CLOSE BEFORE YOU DOZE

My country is extremely dangerous, so we have locks in every door and their reinforcements. So no, im never sleeping with a door open.

closed. Don't want to see no ghosts up for a midnight stroll through my halls.

Closed unless it's too hot in my room. Feels uncomfortable leaving my door open. It'll let me hear killers coming

Open, because my cat sleeps on my bed/floor

Always closed. Gives me a fighting chance against the nocturnal intruders ya know?

Open so my cats don’t kill me.

Closed. I have an 18 year old who has been working the closing shift a lot this summer. I don't want to be woken.

If my door is closed my kitty cat will constantly remind me of that

Closed because I am a mammal and I indulge in the nesting instinct.

Not fully closed, so the cat it's less annoying through all the night.

Closed, safer when fire

closed door because roomates, but open balcony door for maximum fresh air and feels of nature.

Closed almost all the way, but not shut. Need that air circulation otherwise the room gets too hot

Open a crack so the cat doesn't wake me up at 4am.
