Vaccinations for Kittens and Cats

Getting your cat vaccinated is the first of many steps to protect them from catching and spreading infections and diseases. We highly recommend vaccinations for both indoor and outdoor cats. You can start your cat’s vaccination journey when they are 6 to 8-weeks-old. They will continue to receive a series of injections until they are 4-months-old. After this set, they will receive booster shots to keep their immune system strong. To learn more about our vaccines and how they guarantee your cat a longer life, call us at 905.597.7373.

What are in the vaccines and how do they protect my cat?

Vaccines contain a component of the virus they are meant to combat. This introduces your cat’s immune system to the disease and trains it to destroy the virus. When your pet’s immune system is familiar with the virus, it will be prepared to fight off future encounters.

Why must vaccines be given in a series?

We repeat vaccines to ensure your cat’s immune system has a full understanding of how to combat the virus. A kitten’s body contains antibodies passed down from their mother. These antibodies protect your cat’s immune system but only for a while. Eventually they fade away and must be replaced with the vaccinations we provide. We do not know when the antibodies fully exit your kitten’s system so we provide a layer of protection to ensure they are fully covered.

The time has come to begin our reopening process! We cannot believe it has been over a year since we’ve had you all in the clinic but we are excited and eager to welcome you back. Please read carefully below for our updated policies and protocols.


  • Effective October 20, 2021, we will be allowing vaccinated clients in the clinic for doctors’ appointments only. Technician appointments and medication/food pick up will continue to be curbside to control the amount of people in the clinic at any given time.
  • We will be allowing one client to accompany their pet in the appointment. Because we will only be allowing one client in at a time, we will not be able to permit children to accompany their parents. There is a strict one-client rule due to the size of our examination rooms.
  • When you arrive for your appointment, please give the clinic a call at 905-597-7373. A Client Care Representative will either let you know the technician is ready to meet you at the door or will retrieve a phone number if we are not quite ready yet.
  • A technician will meet you at the front door. Please have your vaccine passport/identification ready at this time. The technician will also ask you a few COVID-19 Screening questions before guiding you into the clinic.
  • Face masks are still required to enter the hospital and must be worn properly at all times within the clinic and when interacting with our team members outside.
  • Please sanitize your hands upon entry.
  • Continue the use of credit cards as the preferred payment method.

    We appreciate advance notice for food and prescription refills. Please call 905.597.7373 upon arrival at the FRONT DOOR and a receptionist will be out with your order right away. For faster service, we suggest ordering pet supplies and food through our online store. Delivery is free with purchases over $100.00. It's easy! Just click ONLINE STORE on our website to sign up.
