Every Saturday is Caturday, but there's only one special day reserved for the Shamrock Cat! Happy Pets is offering the cat in the pet shop for 36 Facebook credits, but if you're lucky, maybe you'll get it through a Mystery Box.

Currently, there's no word yet as to when or whether Happy Pets will bring in other St. Paddy's goods since they've been preoccupied by the incremental release of their Wonderland items instead.
