PetVille: Log in and get 2 free Pet Cash every day this week!
But yeah, starting today and lasting for a week, each day players log into PetVille will earn them 2 free Pet Cash. This week is also No Pound Fees Week, which means your your pet won't be confiscated and you won't have to pay to get it released from the pound if you forget to feed it.
Basically, the game is setting up a week where it rewards players for checking in, but also doesn't penalize those who aren't coming back. So whether you're coming back or staying away, if you're a PetVille fan, there's something in it for you.
