Hey Alaxandria, The cost for altering depends on where yu live. I live in NJ and my vet charges around $85 for a spay and $65 for a neuter. Other vets in NJ charge $180 and UP for a spay and $150 and UP for neuter. Now I have heard that vets in other states charge alot more or simmular. People who are going to take any of these ferrets need to call around to get prices but they also need to find a vet that is willing to do it as most have never altered a ferret. I have the 2007 Ferrets year book which does contain a list of vets that do see ferrets for each state. If people would like to contact me and let me know where they live I can send them a list of vets in their state from this yearbook. (I have been doing this for a few years now.) As for prices, I don t honestly know, they would have to call themselves to find out. The other think people can do is contact their local ferret rescue and ask what vet the rescue uses and get the information from them. Debi [Posted in FML 5740]
