Fleas can be a nuisance when they are on your pet. A new mother cat with fleas can be a difficult challenge. Mother cats have to be treated for fleas carefully so as to not endanger her kittens. There are several ways to safely treat a mother cat and her kittens. Mother cats should be treated for fleas so they do not infest the kittens. Fleas can cause anaemia in kittens and can make them ill. The mother cat and kittens should be treated for fleas at the first sign of them.

Use a flea comb to comb the mother cat and the kittens to remove the fleas. Place the removed fleas in a container of soapy water to kill them.

Apply Frontline to the mother cat. Frontline is a topical flea preventive that is safe to use on pregnant and nursing cats.

Wash the bedding the cat or kittens use to kill the fleas.

Vacuum the house to remove fleas from the carpet. Vacuum upholstery as well.


Flea combs are combs with very fine teeth. They are available at pet stores. Use the flea comb on the mother cat and kittens daily for best results. Frontline can be applied to the kittens once they are eight weeks old.


Do not use any form of topical flea preventive on the kittens until they are eight weeks old. Do not use a flea collar on the mother cat or the kittens because they can be toxic to the kittens. Do not use any flea spray or flea shampoo on the mother or kittens as it can be toxic to the kittens.
