This is actually one of the biggest misconceptions about cats.
They are domesticated animals, and they
love the creature comforts of home.
An open (screened) window gives them all of the outdoors they need. (Think kitty TV.)
On average, indoors-only cats live twice as long as outdoors cats, suffer
way fewer illnesses, virtually zero parasites, and remain active (if given attention and play-time with their owners) for virtually their entire lives.
Now for my personal take.
I have always adopted strays, but one of my cats was abandoned young, and spent his first year and a half outdoors as a stray before I was able to bring him in.
He loves to look out the windows, but *never* tries to get out.
I once didn't see him near the door, and had the door open wide as I carried in two armloads of groceries.
You know what he did? He sat there and watched me. When I noticed him, he was literally sitting, watching what I was doing, with a clear line to the outside.
After experiencing the outdoors, and indoor life, he had *zero* interest in "getting out". He knew how good his life was, and wouldn't trade it for the (outside) world.
I even tried taking him out on a leash to roam his old stomping grounds outside our apartment. I had to carry him out, and as soon as he was set down, he turned into a rock, and would not move away from the door. When I opened it, he shot back inside.
So yes, cats are curious creatures, and want to know what is on the other side of a door, any door.
But you can get the same reaction by closing them out of a room in the house for a couple of days. As soon as you open the door they will explore that room like it was a new world.
So please, for your cats' well-being, if you love them, keep them indoors.
