This Is All You Need To Know About The Best Flea Treatment For Kittens


Has Your Kitten Got Fleas?

  1. If the kitten is less than 6-8 weeks old do not use conventional flea treatments. ​ There are other things you can do.  See the video below.
  2. If ​the kitten is over 8 weeks old there are a number of flea control options which are described in more detail below.

How To Get Rid Of Fleas On Very Young Kittens

​Don't use conventional flea treatments on very young kittens (less than 8 weeks). ​ ​The video below has​ useful information showing how to get rid of fleas on very young kittens​.

​There are​ a couple of points to note from the video.

  • Firstly, it is a very good video however, it would have been advisable to begin by bathing around the neck area of the kitten. This is because ​fleas immediately jump to the neck area when kittens and cats are being bathed.
  • Secondly, when the bathing is complete​, don't forget to rinse kitty with some lukewarm water. He may have rinsed the kitty although that was not obvious in the video.

Use A Flea Comb On Kittens

​Use a flea comb after the bath, when kitty has been towel dried.
This is THE best way to remove any fleas that may still be around.

​Remember that even after giving a kitten a flea bath, the fleas will come back​. The flea bath is a very effective solution to immediately take control of the situation but not enough to continue to repel fleas after bath time is over. Most flea shampoos are for use in kittens/cats over 12 weeks old.

Get into the habit of checking your ​very young kitten for fleas daily and use a flea comb to keep fleas at bay. You don’t need to purchase a specific comb for kittens, a comb for an older cat will work just as well.

Another natural way to kill fleas on kittens, in addition to bathing and using a flea comb, is to use Diatomaceous Earth and this is safe for kittens.

Are Fleas On Kittens Harmful to Health?

A flea infestation on kittens can have adverse health effects such as anemia. While this is not often a problem in adult cats it is seen frequently in kittens. The reason being, although we refer to flea bites it is actually the flea sucking a small amount of blood through its proboscis. As a kitten has a low body weight a flea infestation can cause anemia because of the blood loss.  

Are Fleas On Kittens When They Are Born?

​Kittens are not born with fleas however if the mother cat has fleas or the bedding has fleas, it won’t be long before your kitten also has fleas.
