Siri the cheetah cub and Iris the puppy are best friends. And they're just like you and your friends: they play with chew toys, run around in the dirt and develop animal instincts.

When Siri, a 9-week-old cheetah cub, needed a fellow animal to aid her development, Iris was ready to assist. Siri's mother rejected the cub, so the keepers at the Taronga Western Plains Zoo introduced playtime with the 7-week-old retriever and mastiff mix.

Thanks to Iris, Siri is learning how to interact with other animals, and she's looking really cute while she's figuring it out.
