A male cat who has never been neutered is called “whole.” While we might debate the subject of whether an adult male human can be happy and psychologically sound while living a celibate life, there is no question that a “whole” tomcat faces a lot more challenges and hazards than a neutered tom. The simple fact is that an unneutered tomcat feels compelled to mate regularly, which usually involves a lot of rambling and fighting with other tomcats. Most cat owners solve this in the obvious way: they neuter the cat.
