Mine are indoor/outdoor. They can spend their days inside with me in my workspace unless they want to stay outside - which they often do. As Star gets older, she spends more time indoors overall. I often let them stay indoors to sleep, too, but they seem to prefer to go out in any weather except rain. I think they get too warm inside. They like to sleep outdoors on the lawn furniture, and both have cozy igloos inside the garage they can get to thru a dog door.
