I would say it is definitely a cat. Wolves won't walk on logs unless they absolutely have to in a blow down of brush. Cats LOVE to be "up" in the air and walk on logs a lot. If the snow is slick or crusted on an incline, the cats will use their claws to maintain footing. If they are sinking into the snow more than a couple of inches, they will also splay out their claws to stay on top of the snow better. If the yellow on the tree didn't smell like anything, it was probably sap juice from the tree. Cat spray stinks like mad. Either way, kill it
