Although there is no specific course of treatment for non-inflammatory hereditary myotonia, there are certain medications (procainamide, quinidine, phenytoin, mexiletine) that help in decreasing the muscular stiffness and regurgitation. This, however, does not improve the abnormal gait associated with the disorder.
Discourage your cat from strenuous activities or exercise that may increase its respiration, and avoid cold, which may exacerbate the symptoms. Unfortunately, even with treatment, the overall prognosis of a cat with non-inflammatory hereditary myotonia is very poor. Your veterinarian will also recommend against breeding the cat to prevent further progression of the disease to the next generation.
