Without ovulation, she may enter interestrus, which is the combined stages of diestrus and anestrus, before reentering estrus. With the induction of ovulation, the female becomes pregnant or undergoes a non-pregnant luteal phase, also known as pseudopregnancy. Cats are polyestrous but experience a seasonal anestrus in autumn and late winter. [19]
This period of advertised fertility is known as oestrus, "estrus" or heat. [9] In species that experience estrus, females are generally only receptive to copulation while they are in heat [9] (dolphins are an exception).

Dr. MacMillan says, " Panting encourages heat loss by drawing cool air in and expelling hot air back out, as well as the associated evaporation of moisture from the mouth and airways."
Heteropaternal superfecundation is common in animals such as cats and dogs. Stray dogs can produce litters in which every puppy has a different sire. Though rare in humans, cases have been documented. In one study on humans, the frequency was 2.4% among dizygotic twins whose parents had been involved in paternity suits. [6]
