I ordered Profender so that I could easily worm the 20 cats that live on my farm. I was surprised when my package arrived from Singapore. The product I received, however, was sealed and matched the official pictures I had found for the product available in the UK and in Australia. Only 1 of my 20 cats had a negative reaction (skin irritation) to Profender and my cats are no longer symptomatic for worms. I would recommend this product, but make sure your place your order well in advance because it does take a while to reach the United States.
