Sterilization Clinic

Spay and neuter: it’s the caring option

The Mittens-Montreal SPCA Targeted Permanent Sterilization Clinic, supervised by head veterinarian Dr. Gabrielle Carrière, was founded by the Montreal SPCA in March 2015 thanks to a generous anonymous donor. This clinic’s name is a tribute to the donor’s beloved cat Mittens. The medical equipment was donated in memory of Fluffster, her other adored cat.

This clinic’s mission is to help counter the animal overpopulation in Quebec by offering discounted sterilization services to animal guardians with limited financial resources. The clinic has received all the necessary authorizations for its operation from the Ordre des médecins vétérinaires du Québec (OMVQ).

Benefits of sterilization

For females

For female cats and dogs alike, sterilization reduces the risk of tumors in the mammary glands, as well as ovarian and uterine cancers. It also eliminates the problem of pyometritis (uterine infection), which is common in unsterilized females. It furthermore prevents menstrual bleeding in dogs (every six months), excessive vocalization in cats, as well as agitation and sometimes unwanted behaviour associated with heats.

For males

For male dogs, sterilization decreases the risk of prostate problems and testicular cancer and reduces the marking of territory. For cats, it also decreases marking and the strong smell of urine associated with it, all while reducing the risk of conflicts between cats.
