Hello- I have a 14 year old cat that has been on asthma medication most of his life. He tested with a blood sugar level of 360 in November during a check up and started on Lantus with 1 unit per day. He's now on 2 units per day (we're two weeks in) and his numbers are not responding. This morning he tested 399 before breakfast, and they're not dropping much. He's been on wet food for years and I changed to all Fancy Feast classic. Anyone have any suggestions? He weighs 17 pounds and his not losing weight, but drinking a ton of water.
