Trap-Neuter-Release-Maintain Program

It’s a well-known fact: cats multiply at a very high rate. An unsterilized female can give birth to three litters of at least four kittens every year. The “Trap-Neuter-Release-Maintain” (TNRM) method is a effective way to keep the number of street cats down. The method involves trapping, sterilizing and, if necessary, vaccinating and deworming adult cats living in outdoor colonies. These cats, which are feral or semi-feral, are then reintegrated into their environments, where their number gradually decreases thanks to the reduced reproduction.

Our municipal partners

Launched in 2010, the TNRM program is the result of a partnership between the Montreal SPCA and citizens of various cities and boroughs who have seen the positive effects of this method over the years. For example, since the implementation of the program, nearly 7,000 street cats have been sterilized, which means thousands fewer homeless kittens in urban areas.

The public’s participation is essential

The Montreal SPCA prefers to work with people who care about the living conditions of street cats and who also help take care of them. This close collaboration ensures that once sterilized and brought back to their colony, cats will be fed at fixed times and will be able to seek shelter in a warm, dry place.

How to take part in the Trap-Neuter-Release-Maintain Program

  • If you live in one of the boroughs or cities collaborating with the Montreal SPCA and are already taking care of a colony of street cats (or someone you know is), write to us at csrm.tnrm@spca.com or call us at 514-735-2711, extension 2362. Montreal residents who wish to participate must also obtain a mandatory permit from the City.
  • If you live in a municipality or city that does not have a TNRM program and are taking care of street cats, contact your City Council (or City Hall) and encourage them to contact the Montreal SPCA. To find the contact information of your Montreal municipal elected officials, dial 3-1-1 or visit www.montreal.qc.ca.

New procedure: TNRM by appointment only

Concerned about the health and safety of its employees and visitors, the Montreal SPCA has implemented a new procedure for TNRM program participants. Given the limited number of places and our strict COVID-19-prevention measures, anyone who comes without an appointment will be turned away.

Before you capture one or more cats, it is now mandatory to fill out the form below to schedule an appointment with the Montreal SPCA. We will contact you within three business days (72 hours) of receiving your request to arrange a time for you to bring the cat(s) to the shelter for spaying or neutering.

If you have any questions or need more information, please email us at csrm.tnrm@spcamontreal.com or call us at 514 735-2711, ext. 2362. Thank you for your precious help!
