I have used a suspension made by McGuff Compounding Pharmacy @ (877) 444-1155 a couple years back . Dose was 0.5 cc once daily at bedtime for a 2.2 pound ferret. Dose seemed high for that small of an animal, but my vet worked closely with the pharmacist, & because of a ferrets fast metabolism, it was thought that a higher dose was needed. I also worked with Skip fro Skip's pharmacy on the dosing. Skip has the most experience with using it on pets. Did not seem to cause any problems, & he did seem to do better than expected for awhile. So, hard to say. Although, it did not seem to help the IBD, it may have slowed the cancer. I ordered a half bottle, cause the shelf life was only 3 months (I think) & refrigerated it. You got me thinking, my Gracie has Insulinoma, I think I will renew the Rx & try it again on her. Tracy [Posted in FML 7542]
