Felt like drawing something in an ugly sweater, so here you go!
Man, I haven't drawn a Ket in ages. It looks especially derpy today.
This is also a decent size comparison between an Ax Cat and a Ket. Ket are the size of a smallish dog (maybe 20in at the shoulder), while Ax Cats are more like a lioness in height, though they weigh less.
This one is a nectar eater. The feathery bit on the end of the proboscis is used to collect sweet nectar from large flowers (that I have a design for and will submit later). The proboscis is also tipped with a hardened barb that can be used as a weapon. The headshot above shows the tongue in its retracted position. It would be coiled behind the vent.
What appears to be a mouth on the front of the head is actually a vent of sorts, allowing the creature to strain pollen out of the air as it breathes.
The creature has powerful hind legs and large feet, allowing it to run fast and over long distances. It uses its front appendages to balance itself as it runs. The shoulder flaps and forelimbs are also used in aggressive mating displays, in which the large females charge and slam their heads into each other until one is killed or incapacitated. The creatures are otherwise fairly peaceful herd animals.
I'm calling it "Arrowtongue" for now, since it was sort of inspired by a creature of the same name from some speculative space exploration documentary called "Alien Planet". I highly recommend checking it out.
