BUENOS AIRES, Argentina (AP) — A group of people watched three albino rats leap from small baskets into a big cage on Sunday as other rodents hid in makeshift tunnels or searched for applesauce offered by their keeper through the bars at an indoor hall in the Argentine capital.

It's Ratapalooza, an annual event that promotes the adoption of rodents raised in animal facilities or used for research in science labs — once the animals are no longer useful, have outlived their purpose or are just surplus stock.
