Highlighted Reviews
"I used this preventatively so I can’t speak to its ability to kill fleas, but the smell is very strong and lingers. The worst part is my cat lost so much fur. I think my cat was better off without this product."
"Do not use!!! My 5 yr old cat had a allergic reaction. Lost hair, broke out in a rash and had to get antibiotics and steroids plus a pill for 2 days."
Bottom Line
This product is a gamble. While it may work for some, the risk of allergic reactions and the strong odor make it a less than ideal choice for many cat owners.
