Brookfield Zoo in Illinois has announced the birth of two snow leopard cubs.
The cubs, which are currently off exhibit bonding with their 4-year-old mother Sarani, are scheduled to make their public debut in mid-October.
The two females, which each weigh about 10 pounds, were born on June 16, zoo officials said.
Sarani and her 5-year-old mate, Sabu, arrived at the zoo in October 2011 from Tautphaus Park Zoo in Idaho Falls and Cape May County Park & Zoo in Cape May Court House, New Jersey.
Snow leopards are listed as an endangered species by the International Union for Conservation of Nature and experts say their numbers are declining. The Snow Leopard Trust estimates population numbers of the elusive cat are between 4,000 and 6,500 remaining in the wild
