This is certainly a captivating photo, both at first glance and looking closer. The expression on the cat is priceless (I'd probably look like that if I were a cat walking through the snow, too!) Haha.
The bits of dark grass peaking up and soft shadows on the snow are a nice touch, and don't leave the cat as the only form of contrast; but provide a "middle ground," if you will. Honestly, the only thing I might have liked different to either leave out the dark horizon line in the back, or show more of it to balance everything out. The amount of it you showed just feels a little bit distracting and out of place.
But that's a very minor suggestion- the cat and snow is the main attraction and what the viewer will mostly focus on, and this is still a wonderful photo. Good job!!
