Male Cat Sexual Maturity Signs. When do male cats go into heat? Once adults or reached sexual maturity, the female cats (unspayed) are referred to as ‘queen’ and the male cats (unneutered) are called ‘tomcat’.
This can happen as young as four weeks. As you can see, many of these signs are very subtle, and unless you really understand cats and the signs of sexual maturity, it can be easy to miss them. Near the time of birth, a surge of testosterone brings about masculinization of neurons that will later direct male feline sexual behavior;
Other indicative signs are excessive yowling and meowing, irritability, urine spraying, restlessness and just like the male counterparts, attempts to run away from the home.
Perhaps the first sign of a male domestic cat sexually maturing is when their testes drop. For female cats, spaying must be done before reaching six months and for male cats, before reaching nine months. Male cats can reach sexual maturity as early as 5 to 6 months of age. Often, the first signs of sexual maturity are very subtle.
