Toronto Feral Cats

Euthanasia due to homelessness is the largest cause of death in cats.

Estimates place the number of homeless cats in Toronto at between 20,000 and 100,000.

Assuming a pair of cats are left to breed at will, they have two litters per year and 2.8 surviving kittens per litter, the result is a staggering 80 million cats. Source: American Humane Association

Trap Neuter Return

Trap Neuter Return (TNR) programs are proven to be the only humane and effective way to manage feral cat overpopulation. TNR involves trapping, sterilizing, vaccinating, ear tipping and returning cats to their colony – kittens and socialized cats are adopted and a caretaker feeds and monitors the colony daily. TNR is proven.

TNR has been practiced for over 20 years in the UK, South Africa and Denmark. After 1-3 years of TNR colony sizes decrease by 16-32% (Natoli 2006). TNR is an effective long term strategy to stabilize or modestly reduce the size of feral cat colonies as well as improve the health of these cats (Levy, 2003)

Trap Neuter Return is supported by:

American Animal Hospital Association
American Association of Feline Practitioners
Humane Society of the United States
American Veterinary Medical Association
American Society for Prevention of Cruelty to Animals
Association of Shelter Veterinarians
And almost all other major animal welfare organizations including local animal rescue organizations in Toronto

Toronto Humane Society provides access to free TNR for feral cats through our Spay Neuter Services.

Toronto Humane Society is a proud member of the Toronto Feral Cat Coalition (TFCC). The Toronto Feral Cat Coalition includes:

Research to Better Understand the Cat Community Population

In 2017, Toronto Humane Society conducted research using a Geographic Information System (GIS) to estimate the community cat population more accurately. The aim of this study was to enhance the work of the TNR
services provided by Toronto Humane Society, and the organizations in the TFCC.

You can read summarized findings from this research  here.
