The Akron Zoo announced Wednesday that snow leopard cubs were born there for only the second time in the zoo’s history.

Spokesman David Barnhardt said a male cub and female cub were born April 14. They will remain in quarantine in a special indoor area with their mother, Shanti.

Snow leopards are considered an endangered species and are part of the Association of Zoos and Aquariums Species Survival Plan.

The zoo is planning to hold a naming contest for the cubs this summer. They are expected to go on public display at the end of June or early July.

Barnhardt said the cubs weigh about 6 pounds — up from the 1 pound or so they weighed at birth. They are able to walk and are beginning to climb.

After Shanti’s previous pregnancy, zoo staff worked with her to allow them to perform ultrasounds in the hope that she would get pregnant again, Barnhardt said.

The effort paid off.

For the first time in the zoo’s history, the staff was also able to train Shanti to sit during X-rays so that the cubs’ development could be closely monitored, Barnhardt said.

This is Shanti and father Roscoe’s second successful litter at the zoo.

Two male cubs, Raj and Sabu, were born in 2012 and now live at Binder Park Zoo in Michigan and Roger Williams Park Zoo in Rhode Island.

Roscoe, 11, who came to Akron in 2004, remains on exhibit daily at the zoo.

The father does not participate in the rearing process. He will never have direct contact with the cubs.

There are fewer than 150 snow leopards in the United States and only about 4,000 left in the wild. They are native to the mountain ranges of Central Asia and South Asia.

The Akron Zoo is open from 10 a.m. to 5 p.m. daily. Admission is $11 for adults, $9 for senior citizens, $8 for children (ages 2-14). Children under 2 are admitted free. Parking is $3.
