Catty1, thanks for the comment. My vet said the topical (cream) is less effective and more expensive. I am going to pick up the prescription after work today and will ask all kinds of questions then. I have to drive to the company doing the compounding. I will let you all know the outcome.

By the way, Chloe was a complete angel at the Vets when they drew the blood. Juni, on the other hand, a couple of days earlier, was a mess. She wasn't unkind, just a major league wiggle worm. They had to go to two different places on her body to get enough blood. Of course, I figured it would have been in the reverse. ....................Go figure...................... C A T S!!!
