I purchased this from the vet when I brought fleas in from outside. It worked great and immediately. It is a pill form, so you have to be comfortable pilling your cat. I kept my cats quarantined in a bathroom while I was using it. I applied a topical flea treatment, but did not want fleas on the cats or in the house until the topical kicked in. It is a great product to go to if you suddenly find fleas. Lesson learned to keep a topical on all cats at all times.
