Fading kitten syndrome
Kittens that fail to thrive and die soon after birth are often known as fading kittens. The kittens may appear normal at birth but may have a disease that has not yet become apparent. Alternatively, they may develop a condition or contract a disease soon after birth. Unfortunately, it is a common problem and deaths due to fading kitten syndrome in the first 12 weeks may range from 5 to 25%. Of the pedigrees, Persians seem to have the highest kitten mortality rate.
