Purr-fect friendship

JACKSON, N.J. (WPVI) -- Two big kittens are celebrating their first birthdays together at Six Flags in New Jersey.

Nadya the Siberian tiger cub and Zuri the African lion cub are 2 species that would never cross paths in the wild.

Tigers live in Asia and lions live in Africa.

But here at Great Adventure in Jackson, they're partying together.

Staffers raised them and decided they needed kitten socialization.
