I am using the Outdoor Enclosure  for my four cats (I call it the Kitty Condo) to keep them safe at night. They love it and there's plenty of room for all of them. When I step out at night before going to bed they all run straight into the kitty condo so I can lock it up. When I get up in the morning I open it up and let them out. They are outside cats and are free to roam about, but they mostly stay in the backyard. I leave the door open in the day time because they like to go inside to take naps. It keeps them dry on rainy days, they don't even want to come out. I am very happy with my purchase and I think my cats are too.
