*A combination vaccine includes feline distemper, rhinotracheitis, and calicivirus. Some may also include Chlamydophila. **According to the American Veterinary Medical Association and the American Association of Feline Practitioners, cats at low risk of disease exposure may not need to be boostered yearly for most diseases. Consult with your local veterinarian to determine the appropriate vaccination schedule for your cat. Remember, recommendations vary depending on the age, breed, and health status of the cat, the potential of the cat to be exposed to the disease, the type of vaccine, whether the cat is used for breeding, and the geographical area where the cat lives or may visit.
