A pair of young Cougar cubs found orphaned and starving near Missoula, Montana briefly took up residence at the Oregon Zoo before being transferred to a new, permanent home at Tennessee's Chattanooga Zoo.

Oregon Zoo keeper Michelle Schireman described the 5-month-old siblings, one male and one female, as "intensely cute, but far from cuddly."

"The cubs are about as large as medium-sized dogs, with paws as big as bread plates," Schireman said. "Without a mother, young Cougars lack the skills and resources needed to survive on their own.  They started eating right away the first night they were here."

Montana wildlife officials said the pair had been seen around the Missoula area over a period of several weeks, occasionally attempting to raid poultry yards and with no mother in sight. They were eventually captured inside a chicken coop by local residents, who took them to Montana's Fish, Wildlife and Parks (FWP) service.

Montana FWP officials quickly contacted Schireman, who serves as the Association of Zoos and Aquariums' population manager for Cougars, and she worked to find them a home at the Chattanooga Zoo.

Wildlife officials don't know what happened to the cubs' mother, but the two were emaciated when they were first rescued, Schireman said. After two weeks at FWP, with good veterinary care and a steady food supply, they filled out quite a bit. The male cub now weighs 37 pounds and the female weighs 32.

Staff at the Chattanooga Zoo were excited to greet the newcomers.  "They have long history of excellent care and had a space all ready for these cubs," Schireman said.

Cougars — also known as mountain lions, pumas and (in Florida) panthers — live mostly in the western United States and Canada. They weigh from 75 to 150 pounds and have a carnivorous diet both in the wild and at the zoo. Females are either pregnant or raising cubs for the majority of their lives. After three months of gestation, two to three cubs are usually born in a litter and live with their mother for up to two years.

With the exception of the Florida panthers, cougars are not listed as endangered, but they do face many challenges in other parts of the country due to human encroachment and habitat destruction.
