S.K.
My vet who has always been very upforth and honest told me that some of the stuff bought on websites and these catalogs sites cannot be fully trusted. THey said that they have had many people buy from them and their dogs/cats are getting sick and dying. They said they have no idea how they are getting the product b/c it is supposed to only be distributed to veternarians only! They said they think it might be coming from out of the country so even though it has the same brand/box etc.. the ingredients and whats inside is not exact. I actually was just reading on craigslist in the Chicago section a few days ago someone on there writing a tearful warning that they bought from there some flea meds for their cat and shortly after the cat died... Its a risky chance to take
