"My boy needed this medication and this was the first time I have ordered medication through Chewy. It was so easy to select my vet where the prescription was issued from and the price was amazing. Once again Chewy was terrific.. My boy is feeling great and it was so easy to apply Thank you"

"Not sure if it worked yet but caused major hair loss for several of my cats. Followed the instructions and used the same product as what the vet gave me for my other cat. I’m sure it works for some but this was a little scary. Feel very guilty and would not use again."

Bottom Line
