I have an outdoor pool for them, and a portable covered run for outdoor time. We live in the woods and are surrounded by coyotes, owls, hawks, raccoons, dogs, moles, beavers, mountain lions, hawks, snakes, you name it. I supervise them outside in their run, and they are happy inside, especially because it's winter. They love to play in the bathtub and to cuddle. I'm building them a better, more predator proof solution for longer outside sessions when it gets warmer. But, since they're very happy, I'm not too concerned. I also sliced my hand with a wood boring drill bit trying to build one, and 7 stitches later, decided to wait a bit.
