San Francisco's latest walking tour takes people past cats in windows, and apparently, the demand is enormous. Nearly 100 people gathered Saturday for a neighborhood “catwalk,” a free afternoon stroll past the homes of local cats, all volunteered by their owners for a moment in the spotlight. The cats, by all accounts booked and busy, had become local celebrities without lifting a paw. Organizer Lora Lafon told SFGATE the idea began with a Reddit thread inspired by a similar event in Minneapolis. More than 50 households across San Francisco signed up, and interest quickly outgrew what a single afternoon could accommodate. The inaugural walk was capped at 100 people, leaving another 406 on the waitlist and 388 more expressing interest. “We're such a big dog city (love dogs too) that it's been really sweet to see how proud the cat owners are when people stop to admire their babies in the window,” Lafon said. Fortunately for the city's aspiring cat admirers, more walks are in the works, both in San Francisco and potentially across the Bay Area.
