Diseases such as Feline Infectious Peritonitis (FIP), Chlamydia and Feline Leukemia (FeLV) are often given to animals that are at least one year old and delivered on an annual or every third year basis thereafter.
An outdoor cat, on the other hand, should be vaccinated against all of the above, and the owner may even want to consider other vaccines, including Chlamydia, ringworm and Feline Infectious Peritonitis (FIP).
Peritonitis: If the intestinal contents travels into the abdominal cavity, the cavity itself can become infected, a potentially life-threatening condition known as peritonitis.
This condition, called appendicitis, can rapidly evolve into a life-threatening or fatal infection of the abdominal cavity (peritonitis) if not treated immediately.
Infection of peritoneal tissue lining the intestines and the abdomen (peritonitis) may result from bacteria growing in the accumulation of undigested material.
