The English language is rich in adjectives, and some of the most descriptive are those that compare an object (or its attribute) to an animal. I was surprised to see nobody has tried to catalog these terms (or at least not in a way Google can find). So here are the ones that occurred to me:
bovine (ox or cow)
There are surely numerous other animals that have entered the descriptive pantheon (rats, anybody?), but I don't know and can't find terms for them.
