Formal:
* Ungulae: A scientific term for the horny covering of the toes of ungulates (animals with hooves)
* Paws (in some contexts): While technically referring to the feet of mammals, the term "paws" is sometimes used for the feet of large ungulates like horses and cattle.
Informal:
* Feet: This is a general term, but it's acceptable to say "feet" when referring to the hooves of an animal.
* Claws (in some contexts): While not entirely accurate, "claws" can be used for the hooves of certain animals, particularly in informal language.
The best word to use depends on the context and the level of formality you want to achieve.
