The article explains why cats make so much noise when they mate. It starts by describing how the female cat attracts males by meowing when she is in heat. The males then gather around her and compete for her attention, resulting in loud meowing. The mating process can last up to 19 minutes or even an hour, and a female can have kittens from multiple fathers. The article emphasizes the importance of spaying or neutering cats to prevent unwanted pregnancies. Additionally, experts attribute the loudness of the mating process to the male cats' spiny reproductive organs, which can cause discomfort and pain. Females may also experience bleeding and exhibit behavioral changes after mating.
