As an OT example, Starboard who lived till 18 could "sulk" and sit under an old car in the garden. He also had to be outside to greet parents car coming home. He could be happily sitting on your knee even and with a warm fire but when the time came, he had to go outside.

He had a horrible trait with claws when he got older and his back legs were not so good. He could pull himself up, with front legs . claws out, to get to your knee. That could be uncomfortable!
