only most mammalian females are said to be in heat when they want to mate.Heat period is also called estrous and it is part of estrous cycle which is found in female lion tiger cat cattle rat rabbit etc.

Answer 2

Virtually all breeds have two oestrus cycles each year. Initially, the vulva swells and within a day there is a clear discharge, which becomes tinged with blood the next day. This discharge increases in intensity and then slowly diminishes, ending after about ten days. During this time the female becomes more alert and urinates frequently, leaving signals of her impending willingness to mate. Ovulation takes place soon after the discharge has stopped. Only now will the female accept mating. Hormonal changes occur regardless of whether a female is pregnant, which is why there is no simple blood or urine tests to confirm impending motherhood.

Answer 3

"In heat" refers to the estrous cycle, which some female mammals experience. Where the female is receptive to mating, they start producing pheromones to alert males of their species that they’re fertile. During an estrous cycle, the female will continue emitting pheromones and remain in the fertile stage until mated.

This is sometimes seasonal (deer come into heat in the fall) sometimes cyclical (dogs come into heat every 6 months) or a combination (cats come into heat every 1–2 weeks during certain seasons of the year).
