The Complete Guide to Cat Vaccinations: What Every Cat Owner Needs to Know

Vaccinations are one of the most important things you can do to protect your cat's health. But with so many vaccines available, it's hard to know which ones your cat actually needs. This complete guide to cat vaccinations covers everything you need to know.

Core Vaccines (Recommended for All Cats)

1. FVRCP (Feline Distemper)

Vaccine Side Effects

Most cats experience mild side effects that resolve within 24-48 hours:

  • Mild fever
  • Decreased appetite
  • Lethargy
  • Soreness at the injection site

Severe reactions are rare but require immediate veterinary attention:

  • Vomiting or diarrhea
  • Difficulty breathing
  • Swelling of the face or neck
  • Collapse

Indoor Cats Still Need Vaccinations

Even if your cat never goes outside, they can still be exposed to diseases through:

  • Other pets that go outside
  • Visitors who bring in pathogens on their clothes or shoes
  • Escaping outdoors unexpectedly

Celebrating Their Health

A healthy cat is a happy cat. Take photos of them after their vet visits — the carrier ride, the post-vaccine nap, the return to their normal playful self. These everyday moments are part of the bond you share.
