Hi! I am pet sitting a diabetic cat in 3 weeks that is on vetsulin. I am only familiar with Lantus. I also have used a ReliOn meter and this lady uses a alphatrak 2 meter. In the past I saw vast differences when I tested the cat with the 2 meters. He recently was upped to a dosage of one and a half. The vet switched him from one unit to one and a half. I thought it should only go up by 1/4. The last time I tested the cat on a relion meter it showed 202 and the alphatrak showef 354. Any advice would be most appreciated. Thank you!
