How to Tell when a Cow or Heifer is in Estrus. Estrus is defined as the period where a female (in this case, a cow or heifer) is receptive to a male (or, the bull). Estrous, on the other hand, is the whole reproductive heat cycle that a female goes through, from heat period to no heat period (Proestrus, Estrus, Metestrus, and Diestrus).
Answers. 1  The estrous or the heat cycle in a cat consists of estrus, the period of mating, preceded by proestrus (the period where males are attracted to non receptive female cats) and followed by metestrus. The inactive period between the cycles during the breeding season is known as diestrus, and the remainder of the year when the cat is not in heat is called anestrus.
