The length of the Jill (female ferret) season is until she mates, otherwise if she will stays in heat and does not mate, she will eventually die.
Female Ferret "Jills" are "seasonally polyestrous" which means they have multiple heat cycles, in spring and summer.
The ferret is a photoreceptive breeder. Breeding season is triggered by photoperiod, the length of daylight hours, it's when there is more daylight than night or the ratio of daylight hours to night time hours to cause physical changes in their bodies. The Jill or females ferret, if not bred, will go into a prolonged heat, or estrus cycle that can last up to six months, causing high estrogen level that will result in a hormonally induced anemia that can be deadly. Ferret breeders can control a Jill's estrus periods by manipulating light cycles, breeding whenever she comes in heat, or artificially ending an estrus with injectable hormones.
The estrous cycle of pigs is 21 days. Humans have a menstrual cycle which can last from 21-35 days.
The length of estrous for cattle is approximately 21 days. The estrus period last about 18 hours.
The typical menstrual cycle length is around 28 days, but everyone is different. It's also perfectly normal for there to be a few days variation from one cycle to the next cycle.
Estrous refers to the recurring periods of sexual receptivity and fertility in female mammals, commonly known as the estrous cycle. During estrus, females are ready to mate and can conceive. This cycle is influenced by hormonal changes and varies in length among different species.
Ferrets are photoreceptive breeders, meaning the light they see is more than 12 hours of light daily (natural and/or artificial), they will go into season. So it can be anytime of the year depending upon their exposure to light.
The estrous cycle is the cycle of a non-pregnant female mammal that goes through a luteal phase and a follicular phase. Estrus is the period in which an animal will stand to be bred, and is part of the follicular phase of the estrous cycle. An easy way to remember it is that estrous is an adjective and estrus is a noun. Thus, estrous refers to the entire cycle, whereas estrus just refers to the phase in which the animal can get pregnant. Usage: The female chimpanzee can get pregnant because she is in estrus. The female chimpanzee can get pregnant in this phase of her estrous cycle.
The key difference between the menstrual cycle and the estrous cycle is that the menstrual cycle occurs in humans and some primates, while the estrous cycle occurs in most other mammals. In the menstrual cycle, females have a monthly period of bleeding, while in the estrous cycle, females experience a period of sexual receptivity known as "heat" or "estrus." Additionally, in the menstrual cycle, females can conceive at any time during their cycle, while in the estrous cycle, females are only fertile during specific times when they are in estrus.

That depends on how well the chicken is taken care of - but chickens are known to live 12+ years.

no rats have an estrous cycle, not a mestrual cycle.
