Jasmine was started on Lantus insulin in early September. At my vet's recommendation I started at 1 unit, twice daily. I monitored her urine glucose several times daily, as well as noting the frequency and volume of urine and water consumption. If after 7-10 days there was no improvement in her symptoms, I increased her dose by about .25 units/dose and then stayed there for another 7-10 days. Lantus Survey answers: 1.) When was your cat diagnosed with FD? 9/7/05 2.) When did you start using Lantus and how long till regulation? 3.) Are you feeding your cat a low-carbohydrate diet?
