My kitty Oreo has been on Lantus since May, and near as I can tell he's been having these itchy scabs appear on his back. He's still on 4 units twice a day. Just had his latest curve testing yesterday. All his numbers were in the low 100's. I asked the vet if it was possible the Lantus was causing the reaction. He said it was rare, which means it's possible. I asked him if he would consider changing to Levemir to see if that made any difference and he said no. He's not familiar with cats on Levemir. I'm thinking of going to a new vet. What are your thoughts about what I should do?
