The occurrence of snow in the Seattle Tacoma area is extremely variable and usually melts before accumulating to measurable depths. There are winters on record with only a trace of snow but at the other extreme, over 21 inches has fallen in a 24 hour period.
The rabbit's sense of smell is far more developed than that of the human. Moveable folds inside the rabbit's nose assist in the detection of scent. The sense of smell in a rabbit is present at birth, allowing a newborn to find his mother's teat. Rabbits shift their noses up and down when trying to identify a scent; this is called nose blinking..
All of my bunnies have always smelled really good when healthy -- like the fresh hay they love! Their pee has lots of ammonia and can be VERY strong smelling. I've smelled worse from other animals, but the longer it sits until you clean the litterbox, the stinkier it gets. A sick bunny might smell differently than a healthier one. If a bunny has kidney issues, they might have a scent that resembles acetone.
