Two barn cats who live in our climate-controlled pole barn, indoor/outdoor access as they please.
One dog, indoor, usually. My husband built him a huge indoor/outdoor, enclosed kennel for use at any time. This is where he stays when we humans are away from home. We also have Invisible Fence brand electronic fencing enclosing a couple of acres of land for off-leash, monitored outdoor activities.
Two fish, indoor (since they're tropical fish, they probably couldn't survive our harsh Minnesota winters if they lived outside! LOL!).
