Haha, this is ingenious. First, architecture design firm Because We Can turned an underutilized room in their client’s San Francisco home into a mad scientist workshop. Next, they added a Cat Transit System to it, which lets cats travel all over the desks and around three of the four walls. There are even viewing points and secret access points for, you know, times when the feline commuters need to be sneaky or do a bit of spying. Fun stuff.
