Capstar is a fast-acting oral treatment for cats. The tablet eliminates 100% fleas within 7 hours of administration. It effectively starts working to kill fleas within 30 minutes of administration. The easy to administer tablets are odorless and provide protection against fleas without causing any irritation to cats. Capstar for cats contains Nitenpyram, a neurotoxin which blocks the flow of neural messages in fleas thus resulting in the death of parasites. It attacks the central nervous system and kills the parasites. It kills fleas immediately and prevents them from laying eggs. The control of flea infestation also helps in preventing tapeworm infection.
These are the highly effective tablets which I do not have to keep giving to my cats but can be administered anytime at the sight of fleas.
Capstar is good. No question about that.
Really amazed at Capstar's efficacy. Truly a wonderful flea pill for cats.
