In 2018, Proanima implemented a TNRM (Trap, Neuter, Release, and Maintain) program for stray cats living in colonies. This program helps to control cat overpopulation in Longueuil, Saint-Bruno-de-Montarville, Saint-Blaise, Saint-Alexandre and Saint-Jean-sur-Richelieu. In partnership with our client cities, the shelter wishes to improve the lives of cats in the community.

What is it ?

TNRM aims to capture cats from colonies, examine them, vaccinate them and neuter them. If they are healthy enough, they are then released back to their initial area and then maintained in their habitat thanks to the support of volunteer citizens, called “colony guardians.” With the help and support of the shelter, these people provide food and shelter for these cats who can continue to live as they did before.

Why do TNRM?

Developed in many cities and countries around the world, including the United States, the TNRM program is one of the most effective ways to counter the reproduction of stray cats. Non-neutered cats reproduce very quickly, which causes several problems in the community: nuisance in the neighborhood (territorial marking, fights, heat), the development of diseases, undernourishment, the birth of unwanted kittens, surrenders at the shelter, etc.

TNRM allows cats to live in their natural habitat while benefiting from protection and food intake.

What are the steps ?
  • Trap

A cage trap allows for the safe capture of colony cats. These metal cages are built in such a way that the door closes automatically when the cat is inside. Food is placed there to attract the cat. Once trapped, it can then be transported to the shelter for neutering. The process is absolutely safe, the cage does not harm the animal. The shelter offers rental cage traps for citizens of our client cities.

  • Neuter

The procedure here is exactly the same as the one for our cats up for adoption: fasting for several hours before surgery, general anesthesia, physical exam and vaccination (we do the exam while the cat is asleep) and surgery. In order to mark the cat as being neutered, the veterinarian will trim approximately 1 cm from the tip of its left ear. This painless and universal process allows you to easily and visually spot a neutered cat in a colony.

  • Release

Once the cat is awake and has been fed, the volunteer citizen returns to pick it up, and then releases it in its initial habitat, where it can resume its former life.

  • Maintain

Thanks to the participation of citizens living near these colonies, cats are maintained in their natural habitats. We monitor their development and their state of health, and we offer them shelter to withstand extreme temperatures.
