Up to what age are cats fertile? - in detail
Cats, both male and female, remain fertile for a significant portion of their lives, though the exact age range can vary depending on factors such as breed, health, and individual genetics. Female cats, known as queens, typically reach sexual maturity between 4 and 9 months of age, although some may experience their first heat cycle as early as 3.5 months. Once fertile, queens can continue to reproduce until they are around 8 to 10 years old, though fertility may decline gradually after the age of 7. In some cases, particularly in well-cared-for and healthy individuals, queens may remain fertile slightly longer. Male cats, or toms, become sexually mature around 6 to 9 months of age and can remain fertile well into their senior years, often until they are 12 to 15 years old or older. However, sperm quality and libido may decrease with age, particularly after 10 years. It is important to note that while older cats can still reproduce, breeding them poses risks such as complications during pregnancy or birth for females and reduced sperm viability in males. Responsible breeding practices recommend retiring cats from breeding by the age of 7 to 8 years to ensure their health and well-being. Spaying or neutering is also a common practice to prevent unwanted litters and to address health concerns related to aging reproductive systems.
