Star Trek Online has just seen the felinoid Ferasan added to the C-Store. But wait, didn't the game already add Caitians? Yes, but the Caitians are a Federation race, while the Ferasan are exclusive to the KDF, thereby allowing you to play as a kitty on whichever faction you choose. The Ferasan are related to the Caitians but apparently are not quite the same species (presumably akin to the Romulans and Vulcans).
The Ferasan possess only one specific trait, Predatory Instincts, which increases jump height, melee damage, exploit damage, stealth, and perception. Unlocking the race costs 480 Cryptic Points and also unlocks new customization options for Caitian characters on the Federation side. On the other hand, if you just want to have one on the bridge, you can place a requisition for a Ferasan bridge officer for 400 Cryptic Points. So if you've felt that there's a distinct lack of feline members in the KDF, you've now got an option to rectify that situation.
