I have 2 adult cats that were diagnosed with giardia apprx 3 months ago. Panacur was prescribed by my vet. It has not worked. The cats still have diarrhea with some blood in it, & now I have 4 kittens that also have diarrhea. 3 days ago stool samples from the 2 adult cats tested positive for giardia The vet started them all on Panacur again. I just got my bottle of MMS & was wondering if it safe to give both the Panacur & MMS at the same time, or if I should stop the panacur? I am VERY concerned for my cats!!!!
