I just get my lantus from my local pharmacy. However ... I'm in Canada (where lantus is apparently cheaper, and where you don't need a prescription). The feline diabetes website has a list of suppliers for people in the US. I'd look into ordering it soon, so that you don't get stuck with a $300 charge again. I just use the 10ml vials and regular insulin needles. I've also found insulin needles are cheaper online than at the vet. Terumo is a very good needle. Hope you get a good curve at the vet.
