The CSRM Program makes it possible to sterilize stray cats belonging to colonies which some citizens take care of.


The CSRM Program aims to capture, examine, vaccinate and sterilize stray cats from within their colonies. After examination, if they are healthy enough, the cat is then released into their original location and are maintained thanks to the support of volunteer citizens called “Colony Guardians”. These guardians, along with the help and support of the shelter, then provide food and protection to these cats allowing them to continue to live within their colony.


Developed in many cities and countries around the world, including the United States, the CSRM Program is one of the most efficient ways to combat stray cat reproduction. Unsterilized cats reproduce very quickly and thus contribute to creating several problems within the community such as being a nuisance for the neighborhood (territorial marking, cat fights, cat in heat) along with cats developing diseases, being undernourished, and increasing the birthrate leading to unwanted kittens being abandoned in refuges, etc.

The CSRM Program allows cats to live in their natural environment with the benefit of food provision and protection.

The Steps;



Food to entice the cat is placed within TNR (Trap/Neuter/Return) metal cages which are made so that the door closes automatically once the cat is inside. The cat may be then transported to the shelter for sterilization. The process is perfectly safe, does not hurt the animal. Rented cages are made available through the shelter for the citizens of our client cities.



Fasting for several hours before surgery, general anesthesia, general examination and vaccination, and surgical operation. In order to identify the cat as being sterilized, while anesthetized, the veterinarian will provide ear-tipping; surgically removing approximately 1 cm from the tip of the left ear. This painless and universal process makes it possible to easily recognize a sterilized cat within a colony.


The Release

Once awake and fed, the volunteer citizen comes back to pick up the cat to then release it in its original habitat where it can resume its life as before.



Thanks to the participation of citizens living near these colonies, the cats are kept in their natural habitat. Their progress and health monitored, while being sheltered to withstand extreme temperatures.
