What is Cerebellar Hypoplasia (CH)?

Cerebellar Hypoplasia (cer·e·bel·lar hy·po·pla·sia) is a disorder found in cats and dogs which causes jerky movements, tremors, and generally uncoordinated motion, just like ataxic cerebral palsy in humans.  A cat with CH often falls down and has trouble walking or cannot seem to walk at all.  CH in cats is non-progressive, meaning it does not get worse with age.  Symptoms appear at birth, though they may not be noticed until the kitten starts walking at a few weeks of age.  Like symptoms that come on suddenly or later in life are not CH.
