For many years, one of the main mission of KAT Centre Nepal has been ABC Program. Find out more about it here:

what is


KAT Centre Nepal was founded on the idea of helping to solve the overpopulation of street dogs in the Kathmandu Valley. Our Animal Birth Control (ABC) program started in May 2004 and operates along the World Health Organization’s guidelines for the management of stray dog populations. During the ABC program stray dogs and cats are sterilized and vaccinated to control their population and prevent the spread of rabies. 

Without spay and neuter programs, homeless animals are more likely to be involved in accidents, contract diseases, spread rabies, or die from diseases. It is a humane and effective strategy to reduce the number of animals on the streets while also improving the health of those who remain.

Spaying and neutering make a substantial difference!  Just one unaltered female dog and her offspring can produce 67,000 puppies in only six years. In seven years, one female cat and her offspring can produce an incredible 370,000 kittens!



Following are the Steps taken during our ABC program: 

The location and population of street dogs are calculated using scientific methods and mobile applications, particularized for dog population surveys. The results of the street dog survey are reviewed and an appropriate solution for catching the dogs is devised.

Professional dog catchers with ambulances catch the dogs with the cooperation of the community. The dogs who are not friendly are professionally caught using nets.

  1. Examination: The doctors inspect the dogs to see if they are fit for surgery.
  2. Preparation: If fit for surgery, they are prepared for surgery. The dogs are given anesthetic before being cleaned and sterilized by veterinarian assistants in preparation for surgery. In addition, rabies and DHPPiL vaccinations (prevention for immunization of dogs against canine distemper virus, canine adenovirus, canine parvovirus, and canine parainfluenza virus.) are provided.
  3. Surgery: Veterinarians use the Keyhole Technique to operate on the dogs after they have been prepared. A notch is marked on the left ear of the dogs as a marker spayed or neutered dog. The whole procedure takes around 30 minutes per dog and the dog becomes conscious after about 1.5 hours.

The dogs are kept in kennels with care and are monitored to see if they require additional treatment or if they may be released the next day.

If it is determined that the dogs are fit to be released, they are returned to the community. 



Why is it important to spay and neuter a dog?  The single most important thing that we can do to save dogs and cats from all the suffering and death that their overpopulation causes is to spay and neuter them.

Spaying and neutering are routine, affordable surgeries that can prevent thousands of animals from being born, only to suffer and struggle to survive on the streets, be abused by cruel or neglectful people, or be euthanized for lack of a loving home.

Spaying and neutering decrease the health hazards for the animals. As a result of having intact and breeding, animals can contract or develop a range of potentially deadly health issues and transmissible diseases, such as pyometra (an infection in the uterus), TVT malignant (cancerous) tumors, and reproductive malignancies. When an animal is spayed or neutered, these dangers are eliminated.

Sterilized animals live longer, happier lives. Spaying eliminates the stress and discomfort that females endure during heat periods, eliminates the risk of uterine cancer, and reduces the risk of mammary cancer. Neutering makes males far less likely to roam or fight, prevents testicular cancer, and reduces the risk of prostate cancer. Altered animals are less likely to contract deadly, contagious diseases, such as feline AIDS and feline leukemia, which are spread through bodily fluids.

Communities are coping with problems that a failure to spay and neuter causes. The one-time cost of spaying or neutering is far lower than the expense involved in rounding up strays, feeding and housing abandoned animals, and euthanizing those for whom homes cannot be found.

FAQ Question


Spaying and neutering will only reduce or eliminate the behaviors that you do not want, such as aggression and urine marking. Neutered males are less likely to roam, fight, or mark their territory with urine, and spayed females experience less hormone-related moodiness. In exchange, your companions will become more interested in you (rather than finding a mate) and will still protect your family.

No. Cats and dogs become overweight and inactive because their guardians feed them too much and exercise them too little, not because they are sterilized.

Male animals contribute to the companion animal overpopulation crisis even more than females do. Just one unsterilized male animal can impregnate dozens of females, creating dozens upon dozens of unwanted offspring. Neutering also eliminates male animals’ risk of testicular cancer and reduces unwanted behaviors such as biting.

It is best to spay animals before they reach sexual maturity to reap the full health benefits. Spaying your female companion animal before her first heat cycle means she will have one-seventh the risk of developing mammary cancer. Spaying also eliminates female animals’ risk of diseases and cancers of the ovaries and uterus, which are often life-threatening and require expensive surgery and treatment.

Allowing your animal to reproduce only teaches your children irresponsibility. Every year, 3 to 4 million animals are killed in U.S. animal shelters, most simply because of a lack of good homes. Bringing more animals into a world that is already short of homes means that animals in animal shelters will die. Books and videos are available to help you instruct your children about reproduction responsibly.

Even if you manage to find loving, lifelong homes for all the puppies or kittens, which means that there will be fewer homes for puppies and kittens in animal shelters who desperately need to be adopted. And unless you ensure that every puppy or kitten you place is spayed or neutered before going to his or her new home, they can go on to produce litter after litter of offspring themselves. Just one female dog and her puppies can result in 67,000 dogs in six years, and one female cat and her kittens can lead to 370,000 cats being born in seven years.

Spay and neuter surgeries are the most performed animal surgeries. Most animals experience little discomfort (anesthesia is used during surgery, and pain medication is given afterward) and are back to their normal activities within a day or two.
