While we are allowing the Formerly Feral Fellows more freedom, we do keep the fence up across the stairs for most of the day.
Neither of them has made any effort to jump or climb over it, so we presume they’re not bothered by the restriction. Though they are spending more time hanging around near the top of the stairs.
Rufus especially likes the top of that box. It’s a well-padded place to sleep, with plenty of slightly filtered sunlight from the window over the stairs.
Lefty still prefers dark, enclosed spaces, so the lower bunk suits him perfectly.
When we take the fence down and let him wander freely, Lefty frequently comes down as far as the main landing. It’s not just the food bowls that catch his attention.
After a few through-the-fence interactions, ‘Nuki seems to have figured out that Lefty is not as easygoing as his mentor. He’s not a fighter, but he will take a swing at anything he thinks might be threatening him.
I don’t think Lefty wants to be an alpha-kitty, but he does seem to believe in keeping his options open.
As a result, we’ve had several near-interactions like this one, with the two settling down on opposite sides of the floor and elaborately ignoring each other.
Of course, it doesn’t harm the developing relationship any that Rufus casually hangs out nearby, keeping an eye on his protege.
