X-CAT Saves Christmas

On a snowy Christmas Eve, Santa is running late delivering presents. In his haste to get all the gifts delivered on time he accidentally crashes his sleigh into a low flying UFO*. 

The aliens aboard the UFO, furious at the loss of their no claims bonus, decide to vent their rage on the gifts, which have tumbled from the sleigh and landed nearby. 

As they float from their ship, the aliens are stopped in their complete lack of tracks by Earth's first line of defence against alien threats (during the Christmas holidays): X-CAT!

A highly trained squad of cat soldiers, they're here to save Christmas, and possibly worry any nearby upholstered furniture, but mostly it's the Christmas thing.

* I should stress that no reindeer were harmed.
