Can a Siberian live in a condo if play sessions are serious and shelves are usable?

Yeah, a Siberian can do fine in a condo, but don't kid yourself-they're not lazy lap cats. They need real, daily engagement, not just a few minutes with a wand toy. Those serious play sessions you're talking about? Make them count: 20-30 minutes twice a day, minimum. Get them jumping, chasing, and climbing. Siberians are smart and athletic; they'll get bored and destructive if you slack off.

As for shelves, good call. Install a proper cat highway-sturdy shelves, perches near windows, maybe a tall tree. They need vertical space to patrol and observe. Without it, they'll climb your curtains or countertops anyway. If you can give them that and stay consistent with active play, a condo works. Just don't expect them to be a quiet decoration. They'll let you know if you're slacking.
