Can a 4- or 5-year-old male cat still get neutered?
Cats can be spayed or neutered at almost any adult age, depending on their health. Virtually all animal health experts advise that pets undergo these procedures, unless you plan to breed your pet. Neutering is a relatively minor surgery with major benefits, such as desired behavioral changes.
Neutering before cats reach sexual maturity, at about 6 months, can help to prevent the onset of more aggressive mating and territorial marking behaviors. These include fighting, roaming and urine spraying. Once a cat develops these behaviors, it can be hard to get rid of them. Neutering, however, can dramatically diminish these activities, and you can always have your cat undergo training to prevent any residual bad habits.
The neutering procedure itself usually doesn't take much time, and most cats are returned to their owners on the same day. Keep your pet indoors as he recovers.
Lastly, neutering prevents unwanted births and countless tragic deaths, since abandoned kittens often wind up at shelters where they are euthanized if not adopted. Neutering also reduces the risk of your male cat developing certain cancers.
