There are ten Fluffy Cats to choose from: Blue Striped, Orange, Pink, Orange Striped, White, Gold, Blue, Purple, Black and White (not pictured), and Grey Calico (not pictured).
All of them are available for coins, and become unlocked starting at level 20 (the final cat, the Fluffy Grey Calico, is unlocked at level 39). Conversely, if you’d rather not wait to level up to the appropriate state to unlock access to purchase these cats with coins, you can instantly purchase any of them for varying lump sums of Facebook Credits. If you go that route, expect to pay anywhere from 41 to 75 Facebook Credits, depending on the color and level requirement of the pet in question.
