Essential Cat Vaccinations

Essential Cat Vaccinations

Are you wondering which vaccinations are right for your cat? With so many different vaccinations, it can become overwhelming trying to do the right thing for your cat when it comes to vaccinations. Our Moreno Valley vets are here to tell you which vaccinations are essential to protecting your cats from common and serious conditions.


The Importance of Cat Vaccinations

Serious, often deadly diseases spread between cats affect vast numbers of cats and kittens each year. To safeguard your cat from contracting a preventable condition, it’s essential to begin having your cat vaccinated starting when they are just a few weeks old and continuing with 'booster shots' on a regular basis throughout their lifetime. 

Ongoing booster shots “boost” your cat’s protection against a variety of feline diseases after the effects of the initial vaccine wear off. Booster shots for cats and kittens are given on specific schedules. Your veterinarian will let you know when to bring your cat back for their booster shots.

Types of Pet Vaccines for Cats

There are 2 categories of vaccinations that are available for cats, 'core vaccines' and 'lifestyle vaccines'. Our Moreno Valley vets strongly recommend that all cats - both indoor cats and outdoor cats - receive core vaccinations to protect them against highly contagious diseases they could be exposed to.

What Core Vaccines for Cats Protect Against 

Core vaccinations are recommended for all cats. These vaccinations are considered vital for protecting your cat from the following common and serious feline conditions: 

  • Panleukopenia (feline distemper) - FP is an extremely serious, highly contagious viral disease caused by the feline parvovirus. The feline parvovirus infects and kills cells that are rapidly growing and dividing, including cells in bone marrow, the intestines, or a developing fetus. The virus is spread through urine, stool, and nasal secretions. Infection occurs when susceptible cats come in contact with these secretions, or fleas from infected an infected cat. Although infected cats are contagious for only a day or two, the virus can survive for up to a year in the environment, so cats can become infected without ever coming into direct contact with an infected cat.
  • Feline calicivirus (FCV) - This virus spreads through direct contact with the saliva, nasal mucus and eye discharge of infected cats as well as through aerosol droplets spread when an infected cat sneezes. Feline calicivirus is a highly contagious virus that causes a mild to severe respiratory infection, eye irritation and oral disease in cats.
  • Feline herpesvirus type I (FHV, FHV-1) - This highly contagious, ubiquitous virus is one major cause of upper respiratory infections. Spread through sharing of litter trays or food bowls, inhalation of sneeze droplets or direct contact, the virus can infect cats for life. Some will continue to shed the virus, and persistent FHV infection can lead to eye problems.
  • Rabies - Rabies kills many mammals (including humans) every year. These vaccinations are required by law for cats in most states

What Lifestyle Vaccines for Cats Protect Against 

Lifestyle vaccines or non-core vaccines are suitable for some cats, based on their lifestyle. Your vet will advise you as to which non-core vaccines are recommended for your cat. Non-core vaccines include protection against:

  • Feline leukemia virus (FeLV) - FeLV is a retrovirus that is spread through saliva, nasal secretions, urine, feces, and milk of an infected cat; it may be transmitted through cats grooming each other. This condition weakens your cat's immune system and can lead to a lack of appetite, intestinal issues, lymphoma, leukemia, reproductive issues, secondary infections due to immunosuppression, poor healing, chronic respiratory infections, and inflammation of the gums
  • Bordetella - This bacteria is spread through direct and indirect contact with an infected cat. This condition causes upper respiratory infections that are highly contagious. This vaccine may be recommended by your vet if you are taking your cat to a groomer or boarding kennel. 
  • Chlamydophila Felis - Chlamydia is a bacterial infection that is spread through direct contact with an infected cat. This infection leads to severe conjunctivitis (eye irritation). The vaccination for this infection is often included in the distemper combination vaccine.
  • Feline immunodeficiency virus (FIV) - FIV is a retrovirus that is spread through saliva, primarily through cat bites. This virus suppresses the cat's white blood cells, gradually weakening the immune system. Cats infected with FIV will begin to show symptoms related to immunosuppression including inflammation of gums, diarrhea, skin infections, upper respiratory infections, pneumonia, weight loss, poor condition of coat, seizures, behavioral changes

Are There Side Effects?

No injection or medication is without some degree of risk, but we continue to vaccinate because, in most cases, it is much smaller than the risk of the disease itself. That being said, adverse reactions are typically very mild and happen in less than 1 percent of cats.

Common side effects include lethargy, transient fever, and local inflammation. Anaphylaxis and death are, fortunately, extremely rare: about one in every 10,000 vaccines.

Pet owners can minimize the impact of reactions by monitoring injection sites for swelling and any of the other common side effects after vaccinations.

Full Protection From Your Kitten's First Vaccines

Your kitten is not fully vaccinated until they have received all of their injections, at about 12-16 weeks of age. Once they have received all of those initial vaccinations your kitten will be protected against the diseases covered by the vaccines. 

If you want to allow your kitten outdoors before they have received all of their vaccines, it is a good idea to keep them confined to low-risk areas such as your own backyard.
