Hi, Has anyone ever used Vet Rx (for cats) or Ferret Rx in ferrets for upper respiratory problems? I am considering purchasing one or both of these. I know Ferret Rx is a MF product and Vet Rx is not. If they are basically the same, I'd prefer to use the Vet Rx. So, has anyone used either? Which one? Did it work? If you've used both, is there much (or any difference)??? Thanks!!! Kim [log in to unmask] [Posted in FML issue 2965]
