Read What Our Clients Say

  • "This is really a great place for cats. The staff are professional and very knowledgeable. Dr Senshin (not sure of the spelling) provided a lot of great advice about caring for the health of my cat. As a first time pet owner I found everyone there to be very helpful. Even my cat Missy was (mostly) calm during the visit which is the most I could ask for at the vet."
    Bob B.
  • "Wonderful and caring people. I used to live in Missauga but moved to North York, and I will only bring my pet to this clinic."
    GM f.
  • "They were very friendly and treated our cat as one of their own! My cat was a little nervous visiting the vet (as expected) but in no way was she traumatized :)"
