Capstar (nitenpyram) is a vet-recommended, fast-acting flea treatment for cats that begins working within 30 minutes. While it effectively addresses immediate flea problems, it does not offer long-term protection and may require follow-up doses. It's a good choice for quick relief but should be part of a comprehensive flea management plan.
