How do I mate in single player?

At the right age (3-5) look at the map to see where your mate is, then when you find him\her you fight him\her to 30% heath.

What happens if your world is 7

But how do u get one if your cubs old enough? Because my cub is level 11

My cub is level 10 and i found a mate at level 5 last time but the cub is level 10!
