![]() Follicle-stimulating hormone stimulates egg follicles within the ovary to develop and mature, while also stimulating the ovary to produce estrogen. When the brain senses adequate daylight, it releases a hormone called follicle-stimulating hormone (FSH). Thanks to artificial lighting, however, indoor cats may cycle year-round. Outdoor cats have more frequent estrous cycles in the spring and summer, when the days are longer. Their estrous cycle, or heat cycle, is controlled by day length. The Estrous CycleĬats go into estrus, or heat, seasonally. The cervix separates the uterus from the vagina, which is a muscular tube that connects the uterus to the external vulva. This helps keep bacteria from entering the uterus and causing infection. The cervix remains tightly closed much of the time, especially during pregnancy. The uterus is sealed off from the outside world by the cervix. The feline uterus is described as bicornuate, meaning “two horns.” These long uterine horns allow for multiple kittens to simultaneously develop within the uterus. While a human uterus looks like an upside-down pear, the feline uterus consists of two long uterine horns, connected in a “V” shape. However, the uterus of a cat has a very different shape than a human uterus. The uterus of a cat, like the human uterus, is where pregnancy develops. The oviduct is where fertilization with sperm occurs the fertilized egg then enters the uterus to implant in the uterine wall. When an egg is released from the ovary, it travels down the oviduct towards the uterus. There are two oviducts, one for each ovary. ![]() They are connected to the uterus by oviducts, also known as Fallopian tubes. The ovaries are located on either side of the body, near the kidneys. Estrogen is required for the development and maturation of eggs, while progesterone acts primarily to prepare the body and uterus for pregnancy. The female sex hormones play an important role in the sexual development and pregnancy of intact female cats. Female cats are typically born with two ovaries, which begin to produce eggs and sex hormones once a kitten reaches approximately six months of age. The primary sex organ in female cats is the ovary. Now, take a moment to examine your feline companion.First, let’s talk about the female reproductive system in cats. Additionally, mixed-breed cats with a blend of these lineages may also display this characteristic, more frequently observed in males than in females.ĭoes Your Cat Possess a Primordial Pouch? Purebred cats, in particular, often exhibit this feature, although it is gradually diminishing due to evolutionary factors.īreeds commonly associated with prominent primordial pouches include the Egyptian Mau, Japanese Bobtail, Pixie Bob, and Bengal cat. Through the evolution of contemporary cat breeds, the primordial pouch has become more pronounced in certain feline lineages. This additional layer of skin and fat offers protection to the abdomen during confrontations with other cats or animals, reducing the risk of injury. Owing to its fatty composition, the pouch allows cats to store energy reserves, ensuring survival during extended periods without food.Īs a surplus of skin, the primordial pouch grants cats greater flexibility and elasticity in their abdominal region, facilitating stretching and maneuvering. While its function in modern cats is no longer vital, it still serves a purpose on occasion. The primordial pouch is a genetic trait passed down from the early wild cat breeds. Unraveling the Purpose of the Primordial Pouch in Cats Although sometimes concealed beneath the fur, it becomes more apparent when observing the cat’s gait, as it sways rhythmically from side to side. Located just in front of the hind legs, it consists of an accumulation of skin and fat. If your cat has reached maturity, chances are it already possesses a primordial pouch beneath its belly. Let us delve into the fascinating aspects of this peculiar characteristic, enabling you to identify it in your own beloved feline companion.
