Most commonly, CH begins in utero, usually when the expectant mother becomes infected with feline panleukopenia virus (or feline distemper) and passes the condition on to her unborn kittens. Trauma is another cause of the condition, typically blunt force head trauma as the kitten’s brain is still developing.

To prevent the likelihood of her future kittens developing cerebellar hypoplasia, female cats should be vaccinated against distemper prior to pregnancy.

CH is not contagious and can not be passed on to another animal or kitten in the same litter.
