Run of the house, cat flap to garden always open unless it's Zero or Minus degrees when its in-traffic only, cats can't get out.
Cat 1 (Rescue, 6 years next month) will sleep with me / on me when it's cold; for a tiny thing he somehow manages to shove me to the cold side of the bed (just bought a super king duvet in the sales for my double bed).
Cat 2 (Maine Coone, 3 years approx, walked in last year with injury, entire male, now fixed and registered to me) usually sleeps on the end of my bed, like a dog. Big bugger, he's only just figured out he can get through the (average cat size) cat flap thank goodness, as I was leaving the kitchen window open. He also likes the bed in the window above the radiator, and the "window" bed (it's like a shelf hooked to an open top window). Love high spots.
Cat 3 (fully feral, maybe 6yo) pops in and out through the day and night for kitchen snacks, can occasionally be found asleep on the spare bed on chilly nights. He has several beds set up in the garage, door jammed open for him to come and go; favourite last few months is the igloo (that my Cat 1 rejected), which is inside a very stout cardboard box set on it's side and covered with thick rug. He's a lovely thing and once, just once, walked up and rubbed himself along my leg ...
All 3 males and get along OK - Big Boy is 7.4 kilo's and soft as butter.
Found my neighbours (male) cat asleep yesterday in the cubby hole on the new cat tree, startled my Cat 1 who hadn't figured it out as a hiding spot.
God I love my cats. Was supposed to be just the one though.
