The first nearly indestructible ball designed for wild animals is a hit in zoos across the country, zookeepers report.
The ball, called the One World Futbol, will not pop or deflate, even if it's punctured multiple times by such things as a curious lion's teeth, a huge bird's sharp beak, thorns, barbed wire and glass.
One particular fan of the new ball is "Ralph," an elderly, hefty and often persnickety Aldabra tortoise.
"It is particularly difficult to find an enrichment item that can withstand the weight of a 600-pound tortoise and it's even more difficult to find something that a 100-year-old animal will become actively engaged in," explained Margaret Rousser, zoological manager at the Oakland Zoo in California.
"Ralph likes his One World Futbol and can even lay down on it, putting his full 600 pounds of weight on the ball, which just snaps back into shape when he gets up. The resilience of the One World Futbol has made it much easier to enrich a 100-year-old tortoise - Ralph is getting some much needed exercise!" she said.
