Spaying/neutering of dogs, cats and rabbits helps curb overpopulation and limit the number of unwanted offspring. It also prevents a great many euthanasias.

It is also recommended by veterinarians to prevent health problems such as tumors and infections, as well as several undesirable behaviour patterns (scent marking, running away, bleeding, meowing when in heat, etc.) 

Since January 1, 2020, all cats, dogs and rabbits older than 6 months must be sterilized.

For further information about benefits of spaying/neutering, consult the SPCA Web site.
