On those nights you think you've exhausted all surfable channels, remember that San Francisco's government access station isn't all Board of Supervisors meetings and public events announcements. Indeed, the most compelling programming on SFGTV (Channel 26 on your cable dial) is delivered courtesy of the San Francisco Society for the Prevention of Cruelty to Animals. This occasional slide show of pets runs through photos and descriptions of the latest menagerie up for adoption at our local SPCA. As an added and entertaining bonus, the blurbs read like personal ads, revealing tidbits about the pets like "loves cuddles and car rides" or "would be a great companion at an outdoor cafe." Sure, it's a terrific way to find a new doggie or kitty. But even if your landlord doesn't allow pets, the channel will leave you thinking about a lot of things. Like, why do those three rats want to be adopted together? And who names a quail "Dan"?
