Hi, everyone. I called the vet I mentioned, the one who has the lupron for 60.00. Anyway, the sec. told me that the way their office works is that no matter which lupron, 1 month or 4 month, it is 60.00. she said that they monitor the little one to see if they need it every month or can use the 4 month. So if this is beneficial for anyone and you can get to his office in Brooklyn, I hope I have helped in some way. Lezia [Posted in FML issue 3615]
