1 Population control. 2  It is important to neuter a female cat before she can have kittens herself. 3  This happens very quickly depending on breed, time of year born and individual development. 4  The first season usually occurs around six months but can be earlier. There are unlikely to be enough new homes available for them. 2  Health issues. 3  Female cats which are not neutered are more likely to suffer from pyometra (infection of the womb) later in life and with mammary tumours. 4  Queens with infectious diseases may pass these on to their kittens.
