When does a cat have testicles? - briefly
Cats typically develop testicles between the ages of 8 and 10 weeks. By 6 months, they are usually fully developed and visible.
When does a cat have testicles? - in detail
Cats, like many other mammals, are born with their reproductive organs already formed. In male cats, this includes the testicles, which are located in the scrotum. The development of these organs occurs during fetal growth and is influenced by hormonal signals.
At birth, a male kitten's testicles are usually not visible or palpable from the outside because they are still high up in the body cavity, near the kidneys. This positioning is due to the influence of maternal hormones that keep the testicles undescended during gestation. As the kitten grows and develops, the testicles begin their descent into the scrotum.
This process of testicular descent typically occurs between 6 to 8 weeks of age in domestic cats. During this period, the levels of maternal hormones decrease, allowing the testicles to migrate downwards along the inguinal canal towards their final position in the scrotal sac. This migration is facilitated by a combination of factors, including changes in temperature and the action of certain hormones produced by the developing cat's body.
Once the testicles have fully descended into the scrotum, they remain there for the rest of the cat's life. The scrotal sac provides an optimal environment for sperm production, with a slightly lower temperature than the core body temperature. This cooler environment is essential for maintaining sperm health and fertility.
It is important to note that in some cases, one or both testicles may fail to descend properly (a condition known as cryptorchidism). In such instances, veterinary intervention may be necessary to prevent potential complications, including infertility and increased risk of testicular cancer. Regular check-ups with a vet can help ensure the proper development and health of a male cat's reproductive system.
