Happy Pets new Social Breeding lets your pets 'get some tail' next door
In the beginning, players can only breed pets that they've acquired for themselves. Now, with Social Breeding, your pets can breed with your neighbors' pets. All you gotta do is choose a pet, click on it to access the pet menu, then click the little heart icon to submit a breeding request! The old method of social breeding was to lend your pets to other players using the Pet Trader, but this was unsafe because people might not return your pets to you.
We're not sure if it's possible to breed with other players' Limited Edition pets or premium cash pets yet. But we're sure that you can't breed pets that have yet to mature.
