    Spring and autumn are the breeding period of animals, as well as the estrus period of mature cats, and the frequency is very high. Males in estrus urinate everywhere, leaving a scent to attract a mate. Females in estrus produce a shrill cry. If the pet owner does not pay attention, the cat will go away with the smell of the opposite sex, for example, a cat of the opposite sex happened to be walking in the distance, it will absorb the cat in heat. So if a cat is not desexed, it is likely to get lost, after being a stray cat, it will spread more "seed", that is the main reason for the growing number of stray animals.

    After all, a sterilization operation is the best option for cats for not only their health but also the harmony at home. However, many new cat keepers don’t know well about the sterilization operation. Here are the tips for the before & after surgery preparation.

1. Appliances before the operation

Pet Trolley Bag: 

    To make sure there is a place for your cats lie down cozily and steadily after the surgery, a case with hard base is needed.

Pet diapers:

Incontinence might occur to cats due to the anesthetics, so it is better to pad your cat with diapers.

Elizabethan collar or gown:

Elizabethan collars are needed to prevent cats from licking the wounds.


Cats keep their eyes open during operation. Eyedrops are needed to keep their eyes wet, which are often provided by the pet hospital. You’d better confirm with the doctor before operation.

2. Precautions before the operation

1.Clean and disinfect your house before the operation. If the weather is nice, you can air the cat house and other appliances. Cats might hide in the corner after the operation, it could reduce the risk of infection.

2.No Food 8 hours before the operation & No Water 4 hours before the operation. This is because anesthetics could cause vomit or even chokes.

3.Clip their nails several days before the operation to avoid scratching themselves on the day of operation.

3. Operation Procedures

Physical Checks

Physical checks are necessary before the operation. Blood test, biochemical tests and heart rate check are usually included.


Anesthetization is a very important procedure during the operation. Cats could die because of improper anesthesia. Acupuncture anesthesia and gas anesthesia are commonly used. Here is a simple comparison of these two kinds of anesthesia:

Gas anesthesia:

It is safer. Cats breathe in the gas during the operation. If there are any problems, the anesthesia could be stopped in time. Gas anesthetics are also easier to metabolize, so that cats could wake up sooner. At the same time, gas anesthesia is more expensive.

Acupuncture anesthesia:

It is cheaper, but not as safe as well as flexible as gas anesthesia. Due to the difference of drug tolerance, cats might either wake up before the operation finishes or need help to wake up after the operation.


Hair around the operation site will be removed for observation and operation purposes.

Starting the operation

Usually only doctors and nurses are allowed to enter the operation room. What you should do is to wait patiently outside.

4. Care and precautions after the operation

  1. Give your cat a quiet and comfortable environment. It is better to accompany your cat within the 2 days after the operation. If any problems occur, they could be sent to hospital in time. Also, be noted that within 24 hours after the operation, cats might still stay sick and unconscious, so they might be aggressive.
  2. Prepare a cat house with enough space for your cat to lie down. Put it on the floor to prevent cats from jumping. Female cats could be kept in cages for a week to limit their activities, which also helps the would heal.
  3. Cats tend to be sensitive to lights after the operation. Soft lights are suggested at areas where your cat stays.

  4. Don’t feed your cat right after the operation. They can be fed 4-8 hours after the operation, and 1/4 of the normal amount is suggested. Don’t change the cat food, and follow the doctors’ instructions if other supplements are needed. Leave the cat food near the cat house.

  5. Keep your cat indoor 3 weeks after the operation, and also don’t wash your cat to avoid infection.

  6. Pay attention to the healing of the wound. The wound usually scabs 1 week after the operation. It gradually heals after 2 weeks and fully recovers after 3 weeks. Male cats heal sooner than female cats.If the wound is found to have abnormal bleeding, swelling, you should promptly inform the doctor.
  7. Wear the Elizabethan collar for your cat for at least 2 weeks until the wound fully heals. This is very important and necessary to avoid your cat licking the wound.
  8. Medication should be used according to the doctors’ instructions.
  9. Pay attention to the wastes and mental status of your cat. If you find vomit, diarrhea or fever occurring to your cat, contact the vet in time.
