A Comprehensive Guide for Breeders: Vaccinating Kittens at Home

In many places, including the United States, there are no specific legal requirements mandating that breeders vaccinate puppies or kittens before selling them. However, responsible breeders typically ensure that their animals receive necessary vaccinations before they are sold or adopted. This is part of the breeder's commitment to the health and well-being of the animals they breed and sell.

Vaccinating kittens against common diseases is a crucial step in protecting their health and preparing them for their new homes. While many breeders rely on veterinarians for vaccinations, it's legal and possible to administer certain vaccines at home with proper knowledge and preparation. This guide aims to provide breeders with the necessary information and steps to safely vaccinate their kittens at home.

Understanding Vaccinations

Before attempting to vaccinate kittens at home, it's essential to understand the types of vaccines available and which ones are recommended for kittens. Common vaccines for kittens include those for feline viral rhinotracheitis, calicivirus, panleukopenia (FVRCP), among others. You may consult with your veterinarian to determine which vaccines are necessary based on the age, health status, and environment of your kittens.

Age to Administer the Vaccines

Kittens typically receive vaccinations in a series of shots starting with the FVRCP vaccine at around 6 to 9 weeks of age.  The vaccination series typically continues every 3 to 4 weeks until the kitten is around 16 weeks old.


  1. Purchase Vaccines: Obtain the necessary vaccines from a reputable source, such as a veterinary clinic or licensed online pharmacy. Ensure that the vaccines are specifically formulated for kittens and have not expired.

  2. Gather Supplies: Gather all necessary supplies, including syringes, needles, alcohol swabs, and gloves. Use separate needles and syringes for each vaccine to prevent cross-contamination.

  3. Choose the Right Time: Schedule the vaccination when the kittens are healthy, well-nourished, and free from stress. Avoid vaccinating sick or immunocompromised kittens.

Administering the Vaccine

  1. Read the Instructions: Carefully read the manufacturer's instructions provided with the vaccine. Pay attention to dosage, storage requirements, and administration guidelines.

  2. Prepare the Vaccine: Follow the instructions to reconstitute or prepare the vaccine according to the manufacturer's guidelines.

  3. Choose the Injection Site: The recommended injection site for most vaccines is the scruff of the neck or the upper hind leg. Part the fur to expose the skin before administering the vaccine.

  4. Administer the Vaccine: Hold the kitten securely but gently. Insert the needle into the chosen injection site at the appropriate angle and administer the vaccine slowly. Avoid injecting air bubbles into the skin.

  5. Dispose of Supplies Safely: Dispose of used needles and syringes properly in a designated sharps container to prevent accidental needle sticks.


  1. Monitor the Kittens: Keep a close eye on the kittens for any signs of adverse reactions, such as swelling, lethargy, or fever. Contact your veterinarian immediately if you notice any concerning symptoms.

  2. Record Keeping: Keep accurate records of the vaccines administered, including the date, type of vaccine, and batch number. This information is essential for future vaccinations and health records.

  3. Follow-Up Vaccinations: Some vaccines require booster shots to maintain immunity. Follow the recommended vaccination schedule provided by your veterinarian to ensure ongoing protection for your kittens.

Administering vaccines at home can be a beneficial option for breeders, allowing for timely and convenient vaccination of kittens in a familiar environment. However, it's crucial to proceed with caution and responsibility, following proper procedures and consulting with a veterinarian as needed. By taking the necessary precautions and prioritizing the health of your kittens, you can help ensure a happy and healthy start to their lives.
