Csillan Wildlife - Apex Predator

So, our party's hanging out on Csilla for the moment, but I can't find a single mention of any pre-established wildlife on the planet. Rather than take this to mean there isn't any, we've invented some, because, well, what's the fun of tromping around on the surface of a glacier riddled ice planet if there's no snow creatures to encounter?

This thing's definitely a top level predator, I've basically imagined a badger that's evolved under the same pressures as a polar bear. So it's... it's big, maybe equal in mass to a polar bear, but stretched out over a (comparatively) longer, leaner, quicker body. Its feet are huge, to better spread its body weight over the surface of the snow, and entirely covered with fur- no paw pads. Its claws are retractable, keeping them razor sharp; it prefers to stalk, leap, and grip onto its prey in a cat-like style rather than doggedly pursue to the point of exhaustion.
