What is the name of a cat's son? - in detail
The term for a male cat, also known as a tomcat, is indeed "tom" or "tomcat." This designation is widely recognized and used in both colloquial and formal contexts when referring to an intact male feline. It's important to note that this terminology applies specifically to cats that have not been neutered. Once a male cat undergoes the surgical procedure of neutering, the term "tom" or "tomcat" is no longer applicable, as the cat's reproductive capabilities and associated behaviors are significantly altered. The use of these terms helps in clear communication about the cat's gender and reproductive status, which can be crucial for various purposes such as breeding programs, veterinary care, and pet management.
