The Vet has prescribed Lantos Solostar PEN 3cc and needles. Strength _U-100_ Give 1 units SQ BID for diabetes. Adjust as directed. Substitutes permissible. Refills _PRN 1 year_ I can test Luckys Blood Glucose at home and the Vet suggested Alpha Trac Blood Glucose Kit. I recently switched my food from Iam’s adult dry and canned food (reason for the change was for my 23 year old cat Amore- her coat and attitude has really improved since this change) to dry food by Nature’s Variety Instinct Raw Boost Kibble- Duck and Instinct- Grain Free wet food 3 Oz. I grab a mixture of the cans- duck, rabbit, chicken and salmon. Whatever is available. They have a High Protien wet food as well. Maybe I should get this instead for him. I was told only give Lucky canned food and no more dry. I will have to figure out this feeding trick as my Amore does still like some dry food. I was directed to give Lucky one can of food in the morning and one at night. The 3 Oz should be good enough said the doctor. 12 hours apart and then give insulin. I have been looking up the cost for the pens and they are expensive. I found a discount site called Singlecare. Let’s you pay weekly and all this unexpected cost has put a drain in my account for the moment. This site lets you pay a small amount over a set amount of weeks. Thoughts? What they offer is... Lantus Solostar $66.73 3 pen, 3ml of 100unit/ml The script is for 3cc and needles pen not 3ml. Are these one in the same? I am confused. I am sorry I know I am everywhere. My mind is racing and since I found out my left eye lid has not stopped twitching. Ha ha. His Glucose was 406 on Sunday. I have no idea what it is right now. I need direction PLEASE! Thank you all for your kind worlds in my intro post. Helped to settle me a bit. Lucky has no other health issues at this time. He has been my healthy boy! Good question here- what it Lucky does not eat the entire can when I put it down? Do I leave it for a short time then pick it up for the night? Again thank you to anyone and all who can help guide me here.
