Inside/Out. Every critter has a safe zone, here's a couple that ours enjoy! Loki, in one of his usual catatonic states. Tough to see but his right rear foot is about an inch/1.5cm off the rug. Totally inside. Spook,loves the garden,really nice kitty safe zone, also doubles as a great area to hunt in, for unsuspecting prey. Would rather be out than in,but is weather conscious, can't blame her. Outside/ in kitty.
