Hi - my cat was diagnosed last night/today & started on Lantus 1 unit twice a day. He’s been sleeping all day while I was at work, didn’t eat anything. A few bites this morning before the vet appt. Now only a few bites at dinner, probably 2 ozs. I don’t have a glucometer yet. I gave his shot and he’s lying down. He raised his head when he heard a bird. But he’s back down. I’m so scared. Did I do it right? Should I have given his shot when he didn’t eat much? His glucose this morning at the vet was 380.
