How many shots do indoor kittens need?

Indoor kittens need a series of vaccinations to help protect them from common feline diseases. The number and types of vaccines recommended for indoor cats may vary based on factors like the kitten’s age, health status, and lifestyle. However, in general, veterinarians advise indoor kitten owners follow a standard vaccination schedule to ensure their pet stays healthy.

Kitten Vaccination Schedule Overview

The core kitten vaccination schedule recommended by veterinary organizations like the American Animal Hospital Association (AAHA) and the American Association of Feline Practitioners (AAFP) includes the following:

  • 6-8 weeks: First set of FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia) and FeLV (feline leukemia virus)
  • 9-12 weeks: Second set of FVRCP and FeLV
  • 12-16 weeks: Third set of FVRCP and FeLV
  • 16 weeks or older: First FIV (feline immunodeficiency virus) and rabies

Some vets may also recommend additional vaccines like FeLV, FIV, or rabies at earlier timepoints. An annual veterinary wellness exam is also suggested after the kitten vaccine series is complete, with potential vaccine boosters as needed.

Purpose of Core Kitten Vaccines

There are clear medical reasons behind giving indoor kittens multiple rounds of core vaccines:

FVRCP

The FVRCP vaccine protects against three very common and potentially deadly feline viruses – rhinotracheitis, calicivirus, and panleukopenia. Kittens are at high risk for exposure to these viruses from their mothers or other cats. Multiple doses of FVRCP are needed to provide full disease protection.

Rabies

While less common indoors, rabies is almost always fatal once symptoms appear. For public health reasons, rabies vaccination is legally required for cats in most regions. Kittens should receive their first rabies vaccine at 12-16 weeks of age or as mandated by local laws.

FeLV

Feline leukemia virus is easily spread between cats and can cause cancer and immune suppression. Indoor cats may be exposed to FeLV brought home on clothing or through contact with stray/outdoor cats. Kittens are especially vulnerable and typically receive at least two doses of FeLV vaccine.

FIV

Like HIV in humans, FIV causes immune deficiency and makes cats more prone to various secondary infections. It spreads through biting so indoor cats are at lower but not zero risk. Kittens who may go outdoors or live with FIV-positive cats benefit from vaccination.

Other Non-Core Vaccines

Depending on specific risk factors like local disease prevalence, indoor kitten owners may want to discuss non-core vaccine options with their veterinarian such as:

  • FIP: Feline infectious peritonitis is caused by a mutant form of a common feline coronavirus. Some research suggests vaccination may reduce FIP risk.
  • Chlamydia: Chlamydophila felis bacteria can cause respiratory and eye infections in cats. Indoor kittens exposed to stray or shelter cats may benefit from vaccination.
  • Bordetella: This bacterium leads to infectious tracheobronchitis or “kennel cough” in cats. It spreads easily where many cats are housed together so some indoor kittens may be vaccine candidates.

Importance of Completing the Vaccine Series

Giving indoor kittens just one dose of a vaccine is not enough to provide full protection against disease. All recommended doses in the vaccine series should be administered 2-4 weeks apart to maximize immune response. Kittens are especially vulnerable to infectious disease between 6 and 16 weeks of age, so timely vaccination is critical.

Maternal antibodies received from nursing can interfere with an individual kitten’s immune response. Multiple vaccine doses are needed to override this interference and ensure adequate immunity. Indoor kittens who miss or skip recommended shots are at heightened risk of preventable illness.

Booster Shots

After the kitten vaccine series is finished around 16-20 weeks of age, indoor cats require periodic booster shots and wellness exams. For core vaccines like FVRCP and rabies, current guidelines recommend revaccination every 3 years or longer based on a risk-benefit analysis. Your vet may suggest annual boosters for FeLV, FIV, or non-core vaccines depending on your cat’s health and lifestyle.

Risks of Over-vaccination

Giving indoor kittens more vaccinations or boosters than officially recommended can needlessly expose them to risk. Potential concerns associated with over-vaccination may include:

  • Increased chance of adverse vaccine reactions
  • Development of vaccine-associated side effects or tumors
  • Unnecessary pain, stress, and medical costs

There is also no enhanced disease protection from extra shots once an indoor kitten has completed the standard vaccination schedule. Owners concerned about over-vaccination can request antibody titer testing from their vet to check immunity levels before giving additional boosters.

Lifestyle and Environmental Factors

An indoor kitten’s recommended vaccinations may be influenced by unique aspects of their lifestyle and home environment. Examples include:

Known Exposure Risks

Kittens living with FIV-positive or unvaccinated adult cats may need early and extra doses of FIV and FVRCP vaccines. Outdoor cats who interact with the indoor kitten through windows/doors also increase disease exposure risk.

Frequent Boarding

Indoor kittens who are frequently boarded, stay at kitty daycare, or visit the groomer may benefit from bordetella and chlamydia vaccines due to increased contact with unknown cats.

Travel Plans

Kittens who will travel with their indoor owners or relocate to new regions in the future may need non-core vaccines recommended in certain geographic areas.

Medical Issues

Indoor kittens with health problems or weakened immunity may require tailored vaccination plans (e.g. avoiding live vaccines). Breed-specific issues like FIP susceptibility also factor into vaccine selection.

Ask Your Vet

Since every indoor kitten and situation is unique, work closely with your veterinarian to determine the most appropriate vaccination schedule. Be sure to provide your vet information about the kitten’s housing, health background, indoor/outdoor access, and potential disease exposures to help inform vaccine recommendations.

Kitten Vaccination Cost

The average cost for each kitten vaccination ranges from $15 to $35 per dose, with non-core vaccines like FeLV and FIV at the higher end. This results in a total series cost of $90 to $280, excluding additional vet exam fees. Lifestyle factors, geographic region, and clinic can impact costs as well. Pet health insurance can offset some of these preventive care expenses for indoor kittens.

Vaccine Schedule for Indoor Kittens

Age Recommended Vaccines
6-8 weeks FVRCP (feline viral rhinotracheitis, calicivirus, panleukopenia), FeLV (feline leukemia)
9-12 weeks FVRCP, FeLV
12-16 weeks FVRCP, FeLV
16 weeks or older Rabies, FIV (feline immunodeficiency virus)

Non-core vaccine options may also be recommended based on risk factors.

Key Takeaways

  • Indoor kittens should receive a series of core vaccines for FVRCP, FeLV, rabies, and FIV starting at 6-8 weeks old and given 2-4 weeks apart.
  • Completing the full series, typically ending around 16 weeks old, gives the best disease protection compared to a single vaccine dose.
  • Lifestyle, medical history, and potential disease exposures help determine if additional non-core vaccines are advised for an individual indoor kitten.
  • After the initial kitten series, booster shots and veterinary exams every 1-3+ years are important to maintain vaccine immunity.
  • Over-vaccination without clear medical need can put indoor kittens at undue risk of harm.
  • Indoor kitten owners should partner closely with their vet to tailor vaccination recommendations for their pet’s situation.

Conclusion

Indoor kittens have protection needs that warrant following an organized vaccination schedule. Core vaccines like FVRCP and FeLV given as a properly timed series help shield kittens against common but serious infectious diseases. Non-core vaccines may provide added immunization depending on specific indoor risks. Working together with your veterinarian will ensure your kitten receives the necessary shots without over-vaccination. Staying up to date on boosters and check-ups preserves your indoor kitten’s health and quality of life over the long term.
