Houston Zoo has released new photos of two rare clouded leopard cubs born earlier this year and they seriously could not be any cuter.

The two males, named Koshi and Senja appear to be living the good life, rough-housing with each other and a giant stuffed toy.

At just two and half months old the cubs are still too young to be out on show with the public, according to the zoo, who say they still have a couple of vaccinations left before they make their debut. Earlier this year the zoo put out video of them being fed in the zoo nursery.

Kashi and Senja are the first clouded leopards ever born at the Houston Zoo, parents Suksn and Tarak have been residents since 2012.

Zoo veterinary staff hand-reared the cubs away from their parents saying that is the practice with all clouded leopards born in captivity.

In a news release the zoo said the species is so rare it is important to do everything possible to ensure the health and well-being of every clouded leopard "born in the care of man."

Wild clouded leopards live in Central and Southeast Asia in an area ranging from the foothills of the Himalayas down the islands of Sumatra and Borneo, according to the zoo.

They are the smallest of the world's large cats and are famous for being able to run up trees, then rotate their ankles and run back down head first.

The species has become endangered because of habitat destruction and poaching for their distinctive fur. Some in Asia also try to keep them as pets, according to the zoo.

The zoo has seen several animal births in 2014, including a baby giraffe born at the zoo on August 3. Click through above to see all the new arrivals including the awesomely named Fantastic Leaf Tailed Gecko.
