Cats usually do not die after more than 20 days have passed since the onset of cat distemper. At this time, they have developed antibodies to the feline distemper virus and will not be intruded by the cat distemper virus in the future. However, vaccines still need to be injected, because cats can also be invaded by other viruses.
Tip:
As long as a cat can survive for a week intact after being infected with feline plague, it is usually past the critical period.
