Hi, we bought the Furminator at Petsmart, it was on sale. You can watch the PetValu and Petsmart flyers for when they go on sale. I tried to use it, but my scaredy cat Dozer is terrified of the noise. He loves to be brushed so we use the Zoom Groom as well. I didn't find the Furminator worked that well on the short hairs. We bath our guys once every two weeks, and rinse them with apple cider vinegar and warm water, then we brush them, it seems to help.
