Neuropathy associated with transient diabetes mellitus in 2 cats.

A 9-year-old spayed cat that flinched when touched responded poorly to methylprednisolone and phenobarbital. Hyperalbuminemia, hyperproteinemia, hyponatremia, hypochloremia, hyperglycemia and glycosuria resolved with insulin treatment. The flinching disappeared in 2 weeks and insulin use was unnecessary after 6 weeks. A 6-year-old castrated cat with diabetic ketoacidosis and azotemia responded to fluid and insulin therapy but developed a head tilt and insulin shock 2 weeks later. The cat recovered after 6 days of supportive treatment and no longer required insulin after 4 weeks.
