What Vaccines Do Indoor Cats Need?

When you bring home a new cat, you’re adding another member to your family. Our pets trust us to  keep them safe and healthy. That means taking them to their annual vet check ups and making sure they are up to date with vaccinations. 

Both first time and experienced cat owners might have questions about their pets’ shots. Why does my pet need vaccinations? Does it matter if they’re an indoor cat or an outdoor cat? What do I do if my cat has a bad reaction to their vaccination?

Here at Furballfun we love to review and give advice for pet toys, but we also want to educate and help new pet owners with common questions and concerns. In this article we will break down everything you need to know about getting your cat vaccinated.  

Does my cat need vaccinations? 

What Vaccines Do Indoor Cats Need?

Vets and government officials agree: yes.  

Most states require cats 6 months of age and older to have their rabies vaccination. Groomers and  boarding facilities will most likely need a copy of your cat’s rabies certificate (official paperwork proving  your pet has an up-to-date rabies shot) before they will accept your cat for services.  

Just like humans, cats can easily infect each other with several diseases, some of which result in serious  illness or even death. Getting your cat vaccinated is an easy way to prevent them from contracting a  potentially fatal disease.  

What if my cat is an indoor only cat?  

Vets still recommend that you vaccinate your indoor cats. If your cat ever requires boarding or  grooming, or if they do manage to get out of the house, you want to make sure they are protected. It is  always better to be safe rather than sorry.  

What vaccines does my indoor cat need? 

There are three vaccines that vets recommend all cats get. These are referred to as the core  vaccinations and they include: 

1. Rabies: As mentioned before, most states require that cats be vaccinated for rabies. Rabies is a  serious illness that kills many mammals every year. If it spreads to humans, it is fatal if not  treated promptly.  

2. Distemper: This is a shorthand for a vaccine that protects your cat against Feline Rhinotracheitis, Calcivirus, and Panleukopenia (FVRCP).  

Often, this combination vaccine also includes a vaccination for Chlamydophila felis, a  bacterial infection that affects your cat’s eyes.

3. Feline herpesvirus type I (FHV, FHV-1): This virus is extremely contagious and is a common cause  of upper respiratory infections in cats. Once infected, your cat can shed this disease for life and  develop eye problems. It spreads very easily through direct contact with an infected cat’s bodily  fluids including urine, feces, and saliva.  

If you are planning on ever taking your cat to the groomer or boarding them overnight anywhere, you  should strongly consider making sure your cat has their Bordetella vaccine. Bordetella is highly  contagious bacterial infection of the upper respiratory tract.  

When is my cat fully vaccinated?

What Vaccines Do Indoor Cats Need?

Some vaccines require multiple doses to trigger a strong enough immune response in your cat to protect  them from infection. Your kitten should receive their initial vaccinations at around 6-8 weeks and their  final round of shots between 12 and 16 weeks. Once all doses of the vaccines have been administered,  your cat will be considered “fully vaccinated.” This means that they are fully protected against the  diseases prevented by their vaccines. Before then, it is best to keep them inside and away from other  cats.  

For some of these vaccines, your adult cat will require a booster shot every 1 to 3 years to make sure  they stay fully protected. If your cat does not receive their boosters on time, they become susceptible to  infection and groomer’s or boarders may not accept them for services until their shots are up to date. If  you have any questions on your kitten’s initial vaccination schedule or when you will need to bring your  cat in for their boosters, contact your veterinarian.  

Are there any potential side effects my cat might experience? 

Most of the time, your cat will not experience any reaction to their vaccines. When side effects do occur,  they are usually mild and clear up quickly. Rarely, serious reactions can occur, including: 

  • Gastrointestinal upset such as nausea, vomiting, or diarrhea. 
  • May not be interested in food. 
  • Limping, especially in the leg or paw where the vaccine was administered 
  • Redness or swelling around injection site 
  • Hives 
  • Fever 
  • Severe lethargy  

If you have any concerns about your cat’s health or behavior after they receive their vaccines, call your  vet immediately. They will instruct you on how to monitor your cat or to bring them in for follow-up  care.  

Although the media might portray cats as being independent and aloof, the truth is that your feline friend relies on you for their quality of life. Making sure they receive all of their initial vaccinations and any  booster shots they might need as they get older will save you the heartbreak of watching your pet suffer or even losing them to a preventable disease.
