That is a question for the vets themselves. Guinea Pigs are very sensitive to several things, including at least some of what work on other sensitive skin animals. If you give them a call, they will likely be more than happy to ask one of the vets and call you back with the info.
This place is not the vets office, its a place where you give your opinion on the vet clinic it's self. I do recommend animal ark though, they are great and if anyone had flea prevention for guniea pigs it would be them.
@ Cr Logan> I understand this is not the vets office. I asked a question to the public. Thanks for your opinion and answer. Have a good day.
