a black dog and a white cat watching snowy mountain

A black little dog and a white little cat, crouching close together in the snowy night, watching the distant snow-capped mountain. Above the mountain, there is only one star and one moon. The dog is slightly fatter and taller, while the cat is thinner and shorter. From the back, it is evident that they are good friends. No faces can be seen, only ears, and no collars. The atmosphere should be warm.
