Veterinarians recommend all cat get their core vaccines. These vaccines protect cats against widely distributed diseases that have a high mortality rate. A cats core vaccines are feline herpes virus vaccine 1 (FHV-1), feline calicivirus vaccine (FCV), feline panleukopenia virus vaccine (FPV), rabies, and feline leukemia virus vaccine (FeLV). Believe it or not, even your indoor cat is at risk of contracting the disease through fomites, and this is the term used for third objects that work as a transportation system for a pathogenic virus. Thats right, even if your cat does not have contact with other cats, you could certainly bring a virus home on your clothing or shoes!
This article discusses vaccines, their pros and cons, and how you can make the best and safest decision for your cat.
Vaccine Overview
Vaccines are one of the most controversial topics when it comes to both humans and animals, and making the right decision can be a stressful and confusing process for pet owners.
It is essential to understand that no vaccine is 100% safe, and its also important to be aware and acknowledge that vaccines also save lives. Vaccines are preparations of microbes, like bacteria or viruses, that have been manipulated or inactivated so that they dont cause a disease process. By administering these vaccines to the animal, it trains the immune system to protect against the agents targeted by the vaccine.
There are two classifications of cat vaccinations: core and non-core vaccinations. Core vaccinations are recommended for all cats to protect them from common and severe conditions.
They include:
- Rabies: Rabies kills several mammals every year, and there is no cure. Rabies vaccinations are required in most states in America.
- Calicivirus, Feline Viral Rhinotracheitis, and Panleukopenia (FVRCP): This combination vaccine, commonly known as the distemper shot, protects against viral infection rhinotracheitis, calicivirus, and panleukopenia.
- Type I feline herpesvirus (FHV, FHV-1): This is the leading cause of upper respiratory infections.
- Feline Leukemia Virus (Felv): This vaccine is considered a core vaccine for kittens and young adult cats under 1 year of age. Even if it protects against a viral infection spread by close contact, if your cat typically stays inside, you never know if it will jump out or escape one day.
Non-core vaccinations are recommended for outdoor cats.
They include:
- Feline Immunodeficiency Virus (Felv): Also known as cats AIDS, this attacks the cats immune system and is normally spread through bites.
- Feline infectious peritonitis (FIP): Is caused by a coronavirus and normally spread through feces.
- Chlamydophila felis:Is a bacteria that causes respiratory disease in cats. It is normally transmitted from cat to cat, especially in crowded conditions.
- Bordetella: This vaccine is recommended to protect your cat from the bacteria Bordetella, which can cause upper respiratory infections that are highly contagious. Your vet may recommend this if your cat is around a lot of other animals.
What to Consider?
Before giving your pet a vaccine, you should consider your cats overall health and the risk factors it is exposed to, the prevalence of disease in your area, consequences of infection, previous vaccine reaction, vaccine efficacy, duration of immunity, and vaccine properties. As you see, even indoor cats need to be protected against certain viral agents. Its best to consult your veterinarian about your cats vaccination schedule and keep them up to date.
Benefits and Drawbacks of Vaccines
Vaccinating your cat can help protect it and other cats from serious diseases. It will also help protect people from diseases, such as rabies, that can be transmitted by cats.
Vaccinations can also have reactions that range from mild to severe. Every cat can react differently, but there are a few signs you can look out for.
- Swelling: Lumps and swelling in specific areas are also common side effects. A firm bump usually develops at the injection site. Its essential to keep an eye on it for signs of inflammation, growth, or infection. It typically passes within a week, but if it doesnt, and it has grown or seems infected, you will need to contact your vet.
- Lethargy and a mild fever: These signs should be mild and last only 1 or 2 days, but if it goes on longer than 2 days, you should consult your vet.
- Cold-like signs: Some vaccines are administered through your cats nose or eyes, which can lead to cold-like signs, such as sneezing, coughing, and a runny nose, but it should pass within a day or two.
If your cat has a severe reaction from a vaccine, the signs will appear either straight away or up to 48 hours later. These signs include facial swelling, vomiting, diarrhea, and difficulty breathing. Anaphylaxis is the most severe allergic reaction that pets can experience due to vaccinations, and it can be life threatening if not treated immediately.
Several studies have found a link between the FVRCP vaccines excessive use (hyperinoculation) and kidney inflammation. The FVRCP vaccine is made from feline kidney cells; when injected into your cat, the body recognizes them as foreign and produces antibodies.
Unfortunately, those antibodies do not distinguish between the injected kidney cells and the cats kidney tissue, which can result in an autoimmune attack on its kidneys. However, more research is needed to determine whether vaccines cause or contribute to feline kidney disease.
Keeping Your Cat Safe
Vaccines can be a vital part of keeping your cat safe, and your cat is most likely to be safe from a severe vaccine reaction.
Cats are no different from humans regarding needles, so you will need to make their visit to the vet as comfortable as possible. Use a sturdy and comfortable carrier with their favorite toy or blanket so that they can recognize the smell. Cats are sensitive and can pick up on your energy, so its important to stay as calm as possible.
When you arrive home, provide a warm, safe space for your cat to lie down and make sure they have access to water and food. Keep checking up on your cat, ensuring they are comfortable, but also try not to disturb them too much.
Adjuvants are substances added to vaccines that cause inflammation at the injection site, alerting the immune system to the presence of the vaccine. This substance can sadly cause an aggressive tumor that can be fatal, known as sarcoma. Its essential to ask your vet about the vaccines they are using and avoid vaccines with adjuvants.
If a cat requires two vaccines, they can be given at least 1 week apart. This allows time for the first vaccines inflammation to decrease before administering the second. Another valid reason for separating vaccines is that the immune system can only do so much at once.
Conclusion
There are many variables regarding vaccines, and your comfort level after research also plays a role in the decision. Core vaccinations for cats are highly recommended, especially rabies, since the disease can also be passed to humans, and there is no cure.
Cats that live indoors should also be protected since they could go roaming, escape, or be surrounded by other cats when visiting a grooming parlor or boarding facility. While all vaccines are not 100% safe, they also save lives, so weighing the pros and cons is vital to the decision-making process. At the end of the day, we all want to keep our pets safe, and its up to you as the parent to make the best-informed decision.

What Vaccines Does My Indoor Cat Need? (Vet Answer)
The information is current and up-to-date in accordance with the latest veterinarian research.
Learn moreVaccines are designed to protect against a variety of feline diseases, including rabies virus, feline leukemia virus, feline distemper (also called parvovirus), feline calicivirus, and feline herpes virus.
One of the best ways to keep a cat healthy is to ensure that they get the specific vaccines they need, which should be discussed on an annual basis with their vet. Vaccines can consist of core and non-core vaccines, depending on a cats lifestyle (i.e., indoor vs outdoor, how often they might board in a cattery, etc.), age, and other risk factors. Core vaccines are designed to protect against infectious diseases that are either life-threatening or commonly encountered by the majority of cats. Non-core vaccines are those which may not be needed, depending on a particular cats risk factors.
To find out which vaccines an indoor cat generally needs and the timing of these vaccines, read on!
How Do Vaccines Work?
Some vaccines, called killed vaccines, contain inactive DNA or RNA from a pathogen, such as a virus or bacteria. Some vaccines, called modified live vaccines, contain less pathogenic forms of the normal virus or bacteria. Other vaccines, called vectored or recombinant vaccines, contain only a small part of a virus or bacteria inserted into an organism, called a plasmid, that acts to amplify this portion of the virus or bacteria once an animal is vaccinated.
Modified live and killed vaccines are some of the original, more traditional vaccines. Vectored vaccines are a more recent scientific development. Each type of vaccine has possible pros and cons.
After receiving a vaccine, the body recognizes the foreign material contained in the vaccine and produces an immune response. This response takes about 714 days to reach a peak response. This has to do with why vaccines are timed 34 weeks apartto allow for this response and then a settling of the immune system before challenging it again with another vaccine.
Some vaccines made to combat infectious diseases that cats dont routinely encounter, such as rabies, are considered effective after a single dose. Conversely, vaccines made to fight viruses that cats do commonly encounter or that may have antibodies received from their mom generally require a minimum of two doses, sometimes more, depending on the cats age.
What Vaccines Does an Indoor-Only Cat Need?
To determine what vaccines an indoor cat requires, they first need to be separated into kittens and adults.
Kittens receive their first vaccines in what is called a primary vaccine course. This involves vaccines that generally start around 8 weeks of age and continue every 34 weeks until they are 16 weeks of age or older. After 16 weeks of age, most kittens then need their next vaccine one year later.
Ages for a typical kitten primary vaccine course:
- 8 weeks
- 12 weeks
- 16 weeks
Primary vaccines in kittens include their core vaccines (e.g., parvovirus, herpesvirus, and calicivirus), and potentially feline leukemia and rabiesdepending on where they live, and their lifestyle risk factors. Rabies vaccines cannot be given to kittens until they are at least 12 weeks old.
Adult indoor cats fall into two categories for which vaccines they might need. Adult cats that have never been vaccinated generally get primary vaccines (just as a kitten would), along with a single booster 34 weeks later. The reason for this booster is that a single vaccine for herpes, calicivirus, and panleukopenia may not be fully effectivetherefore, a second vaccine provides a bit more protection. Rabies, on the other hand, produces good results after a single vaccine, making a single vaccine sufficient.
Adult cats that received their primary course as kittens generally receive boosters either annually or triennially, depending on the vaccine, how much time they spend outside or boarding with other cats, as well as their age.
What Are the Minimum Vaccines My Indoor Cat Needs?
Once they are an adult, an indoor-only cat that lives in an area without rabies may only need the following vaccines:
The above may be given every three years for some low-risk cats. However, it is always a discussion to have with your veterinarian to determine what vaccines and what vaccine schedule your cat needs.
Are There Instances Where a Cat Vaccine Schedule Might Change?
There are certain instances in which a cat may be deemed not healthy enough to receive a vaccine. Alternatively, it might be too early for them to receive a vaccine. A veterinarian may choose to delay vaccination of a cat for the following reasons:
- Weight loss
- Not eating
- Urinary tract infection
- Upper respiratory infection
- Vomiting
- Diarrhea
- Too soon from the last vaccine
Frequently Asked Questions
What are possible vaccine side effects?
Vaccines, as with any medication, can have potential side effects. One of the more well-known side effects, particularly in cats, is called vaccine-associated fibrosarcoma. Fibrosarcoma is a cancer that forms from the cells forming the connective tissue layer under the skin. There is strong evidence to suggest that a combination of genetics, certain vaccines, and vaccine adjuvants can lead to the formation of these cancers in cats.
Many of these vaccines are now made in a different manner, to not contain adjuvants, and most vaccines in cats are also now given in specific locations of the bodyso that if one of these cancers occurs, the vaccine that may have played a role can be identified.
Some common side effects of vaccines in cats include lethargy, vomiting, and diarrhea. Cats rarely develop anaphylaxis, or life-threatening allergic reactions to vaccines, facial swelling, and hives, the same way many other species are prone to developing. If your cat does experience any reactions to a vaccine, report it to your vet, as the way your cat is vaccinated may need to be adjusted moving forward.
How are vaccines given?
Most vaccines for cats are injections given under the skin and are generally about 1 ml in volume. Other forms of vaccines include nasal drops and transdermal vaccines, but these are uncommonly encountered.
My cat is late for their vaccine. Does that change the schedule?
It depends. If your cats a day or two late, or even a week late, for their annual booster, it is generally not a problem. If your cats more than a week or two late for their primary course booster, they may need an additional booster vaccine.
Is my cat too old for vaccines?
In general, veterinarians no longer consider cats too old for most things. Sometimes, senior cats need the immunity provided by vaccines far more than adult cats. Discuss what risk factors exist for your senior catsuch as time spent outside, boarding around other cats and dogs, and any medical conditionswith your veterinarian to determine which vaccines they recommend and how often.
Conclusion
Vaccination in indoor cats is an important part of preventing serious illness and keeping our furry friends healthy. Vaccines are not just something done once when they are kittens; they are part of a lifelong health plan for your cat.
