Happy Pets: Albino Cat and Dog available when you add neighbors
Now in Happy Pets, new neighbors mean access to new pets -- specifically the Albino Doberman and Albino Siamese Cat. You can buy the Doberman if you have 9 neighbors, while the Cat requires 11 neighbors. Both animals cost 15,500 Coins.
Albino animals made their first appearance back in May, as Trapped Pets, or mystery animals in a locked kennel. That offering consisted of a free albino horse, ferret, parrot, guinea pig, and bunny. (There was also a mini dinosaur involved, but it wasn't an albino dino.)
