Thanks - I have purchased some Ivermectin 1.87 from and have called a local vet. I hope to have the Ivermectin Friday. I am hoping the local vet will let me buy it so I have it today, unfortunately two of them that are in the office right now won't sell it unless you bring the animal in for weighing even though I told them it is a wild chipmunk and I told them I spoke with a rehabber and told them how much I was going to give - good grief! I am hoping the vet I know will be in later on and let me buy some. Like letting mange run through the wild animals is a better option, please, sigh.
