It contains an active ingredient called Nitenpyram, which works by interfering with the nervous system of fleas, leading to their rapid death.

It's often used as a short-term solution to rapidly eliminate existing flea infestations on cats, especially in emergency situations or when immediate relief is needed.  Always consult with a veterinarian before using any flea treatment on your cat to ensure it's safe and appropriate for their specific needs.
