Cheetah and Labrador who grew up together as brother and sister show off their adorable bond

They were raised together as an unlikely brother and sister, and for the past two years Kasi the cheetah and Mtani the labrador have spent their days rollicking around without a care in the world.

Brought together in April 2011, when they were both no more than three-months old, Kasi and Mtani grew up at the Cheetah habitat of Busch Gardens, Tampa, Florida.

The pair became stars as amazing pictures of their strange but touching relationship revealed them to be best friends, but sadly, nature seems to be taking its course as Kasi is re-introduced back to members of his own species.
