24 Aug ODDS FOR LITTERMATES OF FIP KITTENS
Research indicates that if one kitten in a litter gets FIP, that the others are several times more likely, but this is not absolute. If the overall incidence is 5% across the spectrum of young cats produced in a cattery, it could be 10-50% or higher among the remaining littermates. Researchers have seen one kitten in a litter of 6 killed by FIP and also 5 out of 6 develop the disease. Time is the only thing that will determine the fate of healthy siblings.
