No. You can crossbreed only the animals that you have in your zoo
Leopard + White Sifaka
Crossbreed a cheetah and oryx
You can buy it at level 8 I think
Chalarodon with a Tiger Salamander
An Asian white-backed vulture is not listed on the animals on Tap Zoo 2.
i dont think you can get a llama
Its a crossbreed between a Walrus and a Seal and it costs 13 stars
You just visit random neighbors
No. You cannot
connect to facebook
No. You can buy it once you reach level 23 with 16,500,000 coins
It is impossible to get neighbors without Facebook, sorry :(
