Also, he is not as likely to spray in the house, and his urine won t have a strong marking scent. Neutering also eliminates the chances of his developing testicular cancer and greatly reduces his chances for developing prostate infection. The best time to neuter is before the above problems develop, at two to eight months of age. Some veterinarians think that neutering should be delayed until after sexual maturity has been reached at the age of nine to ten months, because they believe that surgery earlier than that will have an adverse effect on bone, stature, and secondary sex traits. This attitude is changing, and neutering of kittens as early as eight weeks old is becoming more acceptable among veterinarians.
Neutering is a simpler and faster procedure than spaying.
The testicles are removed through a small incision in each scrotal sac after general anesthesia is induced. Preoperative and postoperative care is as described above under Spaying. Most cats can be sent home the same day. Recovery is uneventful. However, it may take up to a month for the male behaviors to stop, particularly in an older male.
