Hi everyone! This is Don Rull and I run the Dook Dook Ferret Shelter and Rescue in Jacksonville, FL. I was searching the web for information on the Ferretonin implants and was able to find only limited information. I would like to ask some questions of the group. Please reply directly to me if you have any feedback! The people at Melatek say the implants should be used every 4 months. Does anyone have experience to support this? I have heard that some go every 6 months. Is anyone aware of shelter discounts for the implants? Or alternatively branded products? Do any shelter self inject them or have it done solely at your vet? Also, does anyone happen to know of any sources for pure melatonin powder for compounding? I have been told it can be procured fairly inexpensively, but have not yet found a source. Thank you in advance! Don Rull Dook Dook Ferret Shelter and Rescue [log in to unmask] [Posted in FML issue 4811]
