My cat Bobbles , he was born with Feline Cerebellar Hypoplasia ,In addition to the wobbles, another common symptom of cerebellar hypoplasia is temporary head tremors, or the uncontrollable shaking of a cat’s head (like a bobble-head doll). Also called cerebellar or intention tremors, they are an additional result of damage to the cerebellum.
The tremors, which range in severity, usually occur when the cat is trying to focus on something. They may also be brought on by stress, fear or fatigue, but the tremor usually passes in a few moments. While experiencing a tremor, your kitty may miss her target or fall over, but it otherwise shouldn’t hurt the cat.
