The more I read to learn, the more confusing....I started administering 1 unit insulin, 2ce daily to my 16 y/o cat on 3/10. The vet suggests I administer insulin while Storm eats and that I do a curve next week. Most advice is to give after food intake, and that glucose m-u-s-t be metered before each dose. Are those preference (?) Is a prescription needed for syringes?! The 1st two days, Storm's behavior and movement improved. As of yesterday, looks like his back legs are weaker. Due to his anxiety at vets, I will administer all. But his ear areas are sensitive. Anyone have any experience using a glucometer not at the ear?
