Female Dogs and  Cats

To sterilize female dogs and cats, an ovariohysterectomy is performed. This means excision of the ovaries (that produce eggs) and the womb (where the puppy or kitten would develop).

An incision (a cut using a sterile blade) is made in the midline of the animal's belly, the womb and ovaries are located and removed and the stumps that remain in the body are clamped and tied. The body wall and skin is stitched closed (sutures).

Male Dogs

To sterilize male dogs, a castration is performed. This means excision of both testicles and part of the cord connecting them to the body.

An incision (a cut using a sterile blade) is made in front of the scrotum. Each testicle is pushed out of this opening and the cord is tied closed so that the testicle can be removed safely. The incision is closed with stitches (sutures).

Male Cats

To sterilize male cats, a castration is performed. This is the same as in male dogs (see above) however 2 small incisions are made into the scrotum to access the testicles. These cuts are not stitched closed and are left to heal naturally.

Before Surgery

Usually you will get a phone call the day before your pet's appointment to be sterilized to confirm and tell you when to come to the SSPCA.

If you are unable to attend please let us know as soon as possible so that we can offer your slot to someone else. The waiting list is long and many people are frequently disappointed at how long they have to wait for an appointment.

Do not feed your dog or cat the morning of the surgery. You may need to keep your cat in overnight so they do not search for food elsewhere. One of the staff will let you know what time to stop access to food the night before.

Starving is important as some of the drugs used for sedation and anaesthesia can make your pet vomit. If this happens when they are unconscious or sedated it can cause serious complications-choking or contamination of airways.
