A cohort of 820 cats was identified from among 73 households in the United Kingdom. All of these households were known to contain some feline coronavirus (FCoV) seropositive cats. The cohort was followed for a period of 6 years between 1988 and 1994. The incidence of feline infectious peritonitis (FIP) among these animals was 4.8% during the first 36 months. FIP deaths were highest during the first 6 months after seroconversion, plateaued at a lower level for the next 6 months, and were insignificant thereafter. Cats coming from seropositive households with no previous history of FIP developed FIP over the next 18 months at the same frequency as cats from households reporting FIP losses. Antibody dependent enhancement of FIP, an important phenomenon in laboratory studies, was not observed in nature.
