2-11-21 I took my 10 yr old cat to vet to be treated for what I suspected was a uti because he was peeing outside his litter box. Vet didn't think he had a uti & suspected he was diabetic because he had glucose in his urine. Did blood work. His glucose was 500. Vet gave him an antibiotic shot anyway & talked about diabetes treating options. No symptoms, no weight change. Vet wants me to begin 2 units of Lantus U100 2x a day. I've been checking his bg every 12 hrs at home & his readings range 220-287. He has not urinated outside his litter box since the vet visit. He weighs 15#. I switched him from FF Gravylovers to FF Classic and he no longer has access to dry food. Does he really need 2u 2x a day? I'm so confused.
