In beer judging we use barnyard for feces, ammonia for cat urine, skunky for skunk , and earthy for decay. We also use horse blanket and wet dog (which might be appropriate for the style) and many others. Cat litter is one that is used to describe some of the new popular hops. Even though there may be more descriptive terms they are good enough to get the idea across with out being repulsive. You could always get more descriptive if you felt you needed to. For example woody is very vague. It could be pine, oak, cedar, wet wood or freshly cut. But woody is usually good enough, I hate when they use pungent or mossy. What does moss smell like?
