Information About Neutering Your Cat


Neutering your cat prevents him from breeding and contributing to pet overpopulation.  It also helps prevent elimination, aggression and other behavioral problems that can develop in intact male cats as they mature.  This is especially important for cats that go outside.  Unaltered male cats are much more likely to fight with other cats, putting them at a significantly higher risk of exposure to infectious diseases such as FIV (Feline Immunodeficiency Virus) and FeLV (Feline Leukemia Virus).

The neutering procedure that will be performed is an orchiectomy, the surgical removal of both testicles.  This is done through two small incisions in the scrotum which do not require any suturing.  The surgery is typically done in the morning with your cat going home later that same day after sufficiently recovering from anesthesia.

Discharge Instructions:

Wound Care:  The small incisions on the back end of your cat should heal well on their own and the area needs no monitoring or attention.

Activity:  If your cat is used to going outside, try to keep him indoors for at least two days.  This will keep him from over-exercising which might cause more discomfort than if he just rested.  In addition, your cat may not be as agile or quick for a day or two after surgery, making it harder for him to get out of the way of moving things like cars and other animals.  Most outdoor cats will still readily use a litter box for elimination, so this should not be a problem.  Within common sense limits, there are no restrictions on your cat's activity while indoors.

Multiple-Cat Homes:  Multiple cat households may experience some disruption in the normal interaction of their cats when the neutered cat returns home.  Recognition of the returning cat will be hindered by him having a foreign smell.  This may lead to some unfriendliness at first.  If necessary, consider keeping the convalescent cat isolated for a day or two.

Feeding:  While neutering is important to your cat's health and longevity, the surgery has been shown to decrease a cat?s metabolic rate and possibly increase the ability to store fat.  This means that most cats will gain excessive weight once they are neutered and have finished growing (typically by 7 - 9 months) unless their food intake is limited.  We recommend that you slowly decrease your cat's caloric intake by up to 25% to 30% over the next few months.  This may mean limiting portion sizes, discontinuing free choice feeding and changing from kitten food to an adult formula if you have not already done so.  Obesity in cats has been clearly associated with illnesses and a shortened lifespan.
