How many animals have hooves?

It's impossible to give an exact number of animals with hooves because:

* "Animals with hooves" is a broad category. It includes horses, cows, pigs, deer, goats, sheep, and many more.

* Species are constantly being discovered and classified. New animals with hooves may be found or categorized.

* Species populations fluctuate. Animal populations rise and fall depending on many factors like habitat, predators, and disease.

However, we can say that there are thousands of species of animals with hooves, and they belong to several different orders, including:

* Perissodactyla: Horses, rhinoceroses, and tapirs.

* Artiodactyla: Cows, pigs, deer, goats, sheep, giraffes, hippopotamuses, and camels.

So, rather than a specific number, it's more accurate to say that many animals have hooves.
