All of my cats are indoor only. When I first adopted Sky he kept wanting and trying to go outside but this desire gradually stopped. Sometimes he'll still door dash but lucklily my front door opens up into a hallway. He was a stray and was thought to have lived with a feral colony.

Congrats on your new cat Maddie!!! Like others have said, we need to see some pictures of her. I'm sure she'll learn that living indoors is wonderful. Goodluck.
