Since when, Thomas? Who gave you this erroneous information? Is this information you have firsthand, or something you're parroting from elsewhere? I used it for years with birds and reptiles, and know many others who use it as well. F10 was helping birds for YEARS overseas before it became available recently in the USA.
Perhaps the same vet gave you this info as tried to help you nail an innocent seller to the wall? Don't think we've forgotten ...
