The breeding season is when seasonal breeders reproduce. Various variables can affect when it occurs. [3] A primary influence on the timing of reproduction is food availability. Organisms generally time especially stressing events of reproduction to occur in sync with increases in food availability.
The breeding season for Geoffroy's cats lasts from October to March. During this time, the female comes into estrus for periods of up to twelve days, between three and five weeks apart. Mating during this time is brief and frequent, often taking place on a high ledge or similar site. [6] Gestation lasts for 72–78 days. [9]
The energy expenditure of chasing and fighting during the breeding season can result in a buck losing an immense amount of weight, with some research documenting losses of as much as 20% of body weight with some sources showing body mass losses of up to 30%. [11] On average, a buck before breeding season can weigh up to 180 pounds (82 kg).
A captive male Pallas's cat housed under natural lighting conditions showed increased aggressive and territorial behaviour at the onset of the breeding season, lasting from September to December. Its blood contained three times more testosterone than in the non-breeding season, and its ejaculate was more concentrated with more normal sperm ...
For example, a cat's gestation normally takes 58–65 days while an elephant's takes nearly 2 years (21 months). [3] However, growth does not necessarily determine the length of gestation for all species, especially for those with a breeding season. Species that use a breeding season usually give birth during a specific time of year when food ...
Cat owners have been urged to avoid the newly emerging “bullycats,” a hybrid breed that resembles the controversial XL bully dogs. Breeders in the US have created the new cat breed by mixing ...
Ovulation occurs 24–48 hours after the luteinizing hormone peak, which occurs around the fourth day of estrus; therefore, this is the best time to begin breeding. Proestrus bleeding in dogs is common and is believed to be caused by diapedesis of red blood cells from the blood vessels due to the increase of the estradiol-17β hormone .
During the mating season, Iriomote cats become active during the day as well. [11] Breeding females are more active than nonbreeding ones during the late night and morning hours. [24] Outside the mating season the cats live in solitary, but when they begin breeding they act together.
