We've got a catio, best thing ever. It's a catio coming off the window with all shelves, which then goes into a 5 foot run, then into a larger catio. Full of shelves, scratch post, planters of catgrass, boxes, ropes hanging down with catnip toys, a human swinging chair and its covered in fairy lights. It's amazing. Smell my cats utter bleeping wealth. Honestly they don't say miaow, they say wealth. They have real fur coats on too. Mr Best thinks the man next door is a knob, so he put a shelf in there right by their conservatory window, and my cats just stare in like the nosy bastards they are.
