Three Asian fishing cats have been born at an Ohio zoo as part of a program aimed at protecting endangered species. The Columbus Zoo and Aquarium said Tuesday two male kittens and one female kitten were born July 29. The kittens are with their mother in a secluded area until they're several weeks old. ~ Fishing cats are found in southern Asia. They are skilled swimmers with webbing between their toes and eat primarily fish. Adults range in weight from 15 to 35 pounds. ~ The kittens each weighed less than half a pound at birth. They're the first for a pair of fishing cats that arrived at the zoo last year as part of a species survival plan. The zoo says water pollution, clearing of forests and exploitation of fish stocks threaten the species. In the wild, the nocturnal fishing cats live in densely vegetated areas near marshes, mangroves, rivers and streams as well as in tropical dry forests.
