Insulin Therapy in Small Animals, Part 2: Cats.

No insulin formulation should be considered best by default for management of feline diabetes. Rather, the choice of insulin formulation should be tailored to the specific clinical situation. In most cats that have some residual beta cell function, administering only a basal insulin might lead to complete normalization of blood glucose concentrations. Basal insulin requirements are constant throughout the day. Therefore, for an insulin formulation to be effective and safe as a basal insulin, its action should be roughly the same every hour of the day. At present, only insulin glargine U300 approaches this definition in cats.
