If Cissy and Mione come back negative for CL they will be getting dosed with Case-Bac. I know its supposed to be only like 80% effective but thats 80% more than 0% and I think that makes it more than worth it for me. I'm not convinced I'll be able to get it from my vet but I will be willing to go to the US. Can you pick it up in stores there? I'll be going into NY if I go to the States.
