About us

CTSN was formed in 2000, for the aim of trapping, sterilizing and re-releasing of feral and stray cats as an alternative method of controlling the population explosion of feral cats in the greater Cape Town area.

CTSN was founded in response to a need for help in caring for and controlling the populations of the numerous feral cat colonies in the area using sterilization, which is more effective and more humane than euthanasia.

Concerned members of the public who regularly feed feral cats colonies were reluctant to approach any of the larger animal welfare societies for help, as they were informed that the cats would be killed by most of these organizations.

Euthanasia is not effective method of controlling feral cat populations. Other cats soon move in to the vacuum created by the removal of a colony and the cycle continues.
The network consists of:

  • A coordinator and volunteer workers.
  • A number of feeders (individuals or groups of people who feed the colonies and monitor the health of the colony, population status, and any new additions to the colony)
  • Trappers who trap unsterilized, injured or ill cats.
  • A number of Veterinarians were approached and several agreed to donate the cost of two free sterilizations at their practices to CTSN on a monthly basis. Additional sterilizations are done for a nominal fee.


Feeders approach CTSN for help after hearing about the organisation through friends, veterinarians, animal organizations or other interested parties. The details of a particular cat colony are noted, and the colony is placed on CTSN'S waiting list. A CTSN volunteer then goes out to the colony, assesses the situation and educates the feeders on when, where, how and what to feed the cats. Any health or other problems are noted and reported to CTSN.

The feeder is contacted a few days before trapping is scheduled. Cats are not fed for 24 hours prior to trapping. The trapper then goes out to the colony on the scheduled day. Chicken or tinned fish is used to bait the traps.

The trapped cats are transported in their trapping cages (covered, in order to reduce Stress) to a holding area. Every effort is made to keep them calm; they are placed in a quiet, dark area and their cages are kept covered.

The following morning they are transported to the veterinary clinic and collected in the afternoon. Water and pellets are placed in their cages while they are still sedated. They are taken back to the holding area to recover fully from the effects of the anesthetic and are released back into their colonies the following day. A small notch is made on an ear tip to identify sterilized cats. Records are kept on each colony dealt with. These records are filed for future reference (statistics, queries, articles to be written, etc.

Euthanasia is only ever carried out by a registered veterinarian after a thorough examination of the cat, and after all parties concerned are in agreement that the decision is in the best interests of the animal.


Small kittens (4 to 6 weeks old) are removed from colonies. They are bathed, dewormed and treated against fleas. Anybody wanting to adopt a kitten is interviewed and made to sign a contract agreeing to sterilize the cat and provide any necessary veterinary care.

Home  checks  are  done  and  adopters  are given   help,   support   and   guidance   where necessary, e.g. advice on introducing cats to dogs, the taming of feral kittens, etc SERVING THE COMMUNITY CTSN also undertakes to help the impoverished people and homeless living in informal settlements care for their cats - including primary health care and sterilization.


In most cases, relocation of feral cats is not necessary. Feeders love these cats, which control the vermin population. Once all the cats in a colony are sterilized, we see that they form themselves into social units and are very reluctant to allow outsider cats in. Sterilised females, in particular, become very dominant. They contribute to the environment by keeping the rodent population under control.
