Of affected kittens that are two months or less of age, 95% die regardless of treatment. Kittens that are more than two months old have a 60-70% mortality rate with treatment and a nearly 100% mortality rate if not treated. Adult cats have a 10-20% mortality rate if treated, and an 85% mortality rate if not treated. Elderly cats have a 20-30% mortality rate if treated and a 90% mortality rate if not treated.
