I wrote the previous review of this product. My cat didn't have mange, as I had thought, and so I'm not qualified to rate this product at the present time. I will keep the product and will use it on my outside dogs in the spring. I'm sure it will work great on their mange!
I drenched my cat a couple times with this product and spot treated her mange, also. The product helped somewhat, but didn't irradicate the mange. I am also affected by the mange mites and I spot treated which helped to relieve the itching some.
