Along the Bowery in Manhattan, people waited in a line that would challenge any fancy art gallery opening or exclusive New York City club.

But what brought these people here on a cool sunny Thursday afternoon wasn't art or exclusivity, it was cats.

Well, cats and coffee.

Cat Café opened its doors Thursday, for cat lovers and the cat-curious to enjoy complimentary "cat'achino" cappuccinos, talk cat health and learn about cat adoption with 16 cuddly cats. Pet food brand Purina ONE is hosting the café as a pop-up shop, lasting only through Sunday, but organizers hope the event encourages cat health awareness and adoption.

"The goal of what we're doing here is try to start a conversation about cat health. What better place to do that then over a cup of coffee with some friends in a café? We thought if people are going to be talking about cat health, you should be among your subjects and have cats all around you," said Niky Roberts with Purina ONE.
