Other species females of non-primate vertebrates, for example rats, mice, horses, pig have this form of reproductive cycle.

Polyestrous Animals - Estrous cycles throughout the year (cattle, pigs, mouse, rat).

Seasonally Polyestrous Animals - Animals that have multiple estrous cycles only during certain periods of the year (horses, sheep, goats, deer, cats).

Monestrous Animals - Animals that have one estrous cycle per year (dogs, wolves, foxes, and bear)
