Input: I was pleased with this product for about 2 weeks, then I noticed my cat itching again. I saw fleas on her back legs. I have an indoor/outdoor cat (a feral cat I feed) that brings in fleas to my sweet indoor elderly cat. I had hoped this collar would protect my elderly cat from the fleas, but it does not.

Does not last as long as they state. Not even one month!
