This pair of little big cats pounce and prowl like any curious kittens, blissfully unaware they are two of the rarest leopards in the world.
Baby Amur leopards Argun and Anuy were born at the Wildlife Heritage Foundation (WHF), a conservation charity based in Smarden, Kent, which supports rare and endangered big cats.
It is thought no more than 40 Amur leopards survive in the wild.

Smarten up: Mum Xizi gives one of her babies a wash
Mark Edgerley, who runs the centre where the eight-week-old cubs were born, said the pair were beginning to become more confident and could often be seen playing together in their enclosure while their mother, three-year-old Xizi, looks on.
They have no access to their father, Artur, six, who is their biggest danger due to the male leopard's lack of paternal instinct.
Mr Edgerley said: 'They are like little kittens; they chase straw and if they see a bit of sunlight falling on the ground they will go after that. They look as if they had not got a care in the world.'
Precious cargo: Amur leopards are an endangered species
He said the cubs are still suckling from their mother but are 'just starting sniffing around and playing with bits of meat and bone'.
When they are fully grown the leopards will, like all the other big cats at the centre, eat up to 18kg (40lb) of meat a week, including a mixture of horse, calf and rabbit meat.
Two's company: the cubs prowl around their enclosure
The Amur leopard's natural habitat is the Russian Far East, within a forest region known as Primorskii Krai where the River Amur flows.
There the animal is under threat of extinction due to the burning of the forest to make way for agricultural land.
A strategy to increase their numbers is to establish a second population at a separate site by breeding animals in captivity.

There are around 140 Amur leopards living within a carefully managed European breeding programme, which the WHF is a part of, but Mr Edgerley said that Argun and Anuy will never be released into the wild.
'Animals that are bred in captivity cannot just be let loose to fend for themselves. It won't be first-generation zoo animals that are released but second-generation ones,' he said.
