Treatment varies with the type of metabolic defect and extent of your cat's symptoms. In most cases, there is little to be done for those suffering from metabolic defects. If the cat suffers from seizures, decreased body glucose, or brain issues, it will need to be hospitalized and placed in intensive care.
Depending on the type of metabolic defect, diet restrictions may be put in place, especially if the defect has led to hypoglycemia. Discuss with your veterinarian about a feeding plan and do not allow the cat to exercise strenuously.
Overall prognosis depends on the type and extent of the metabolic defect, but a veterinarian will always advise against breeding the cat due to high probability of passing along the defect.
