"Capstar for a kitten is very dangerous and harmful for newborn kittens. Capstar should only be used on kittens after they are 4 weeks old. For newborn kittens, you should perform grooming instead of using flea treatments."

Problems with Capstar

Capstar tablets will only kill adult fleas, but you will have to use a different flea treatment for your cat if you are concerned about flea eggs.
