What other health issues or conditions do CH cats have?

CH cats are more prone to chipping their teeth, may get injured more frequently from jumping/tumbling off of furniture, but apart from general issues with uncoordination, there are none.  CH cats can get the same illnesses and medical conditions as non-CH cats.  Some members of the community have CH cats who are also blind, deaf, or have seizures (though none of these are common, just like with non-CH cats).
