Capstar is an oral flea tablet for cats that starts killing adult fleas within about 30 minutes of dosing. It works for roughly 24 hours, so it is a fast knockdown rather than a monthly preventive. Owners use it to break a flea outbreak, calm an itchy cat quickly, or clear fleas before starting a longer-acting product. It has no lasting protection, so it pairs with a monthly flea control for full coverage.

Owners rate Capstar highly for speed, saying fleas drop off within an hour and itching eases the same day. Many keep it on hand for outbreaks and use it alongside a monthly preventive. Complaints center on its short action and occasional vomiting or drooling after dosing.
