The estrous cycle (British spelling, oestrous) is the main reproductive cycle of other species females of non-primate vertebrates, for example rats, mice, horses, pig have this form of reproductive cycle. There are also a variety of different forms:

  • 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)
