Burned my cat

You read that right. When I used this product on my 6 year old cat for the first time, following all of the instructions, the product chemically burned my cats fur

You read that right. When I used this product on my 6 year old cat for the first time, following all of the instructions, the product chemically burned my cats fur off and left him with a bald spot and skin irritation. I couldn’t believe this has so many good ratings when it can do that!

I expected better from Capstar

While the Capstar tablets for quick flea eradication is excellent, these topical treatments dropped the ball. Pretty much completely ineffective. I don’t know if it’s the Fipronil that doesn’t work or their formulation, but I am still battling fleas.
