How to detect fleas in cats


Knowing if your cat has fleas is not easy. We give you all the tips to detect them, we explain what fleas are the ones that attack your cat and the flea's life cycle.

Fleas, the most frequent parasites of the cat

And the most frequent of all is the so-called cat flea, scientific name, Ctenocephalides felis, is the most abundant (this species of flea is, curiously, one of the most frequent parasites also of the dog).

"The flea of ​​the dog and the cat are very similar but it is the flea of ​​the cat the most abundant. Both can parasitize cats, dogs and people"

A flea is relentless when looking for an animal to feed, is strong and fragile and can give thousands of jumps of about 30 cm away each of them to find their host. The distance you can travel is amazing.

The most normal thing is that a cat is infested with the fleas that are in the environment, in its surroundings, although it has been discovered that the flea of ​​the cat has a great capacity to be transmitted between our feline companions, taking advantage of the social behavior between cats that live in the neighborhood.

In addition, immature female fleas are the most likely to change hosts, surely seeking to form a new offspring.

What is the flea life cycle

When the female flea manages to reach a cat, it begins to itch almost immediately, feeding on its blood and in one or two days it is already able to lay eggs on its skin.

You can lay up to 50 eggs a day, which will continually fall to the ground.

We could say that the cat involuntarily collaborates in the diffusion of fleas throughout the house and in the places where it wanders.

Only one to ten days are needed for the eggs to hatch and leave the larval 1-2 mm larvae.

The larvae move until they find a place protected from light: carpets, carpets, cracks in wooden floors, under furniture these are your favorite places.

They feed primarily on the feces of adult fleas until they evolve and form a cocoon into which they will transform. Within three to five weeks they will become adult fleas and look for another host to feed and continue their cycle.

Would you recognize the signs that indicate the presence of fleas in your cat and in your house?

Fleas move easily over the cat's coat and can therefore be placed anywhere, but it is easier to find them in the ears, on the neck, on the abdomen and at the end of the back.

  • We and our family are also very appetizing for fleas, so they may bite us, especially to children who usually will explore all corners of the house.
  • The fleas can transmit a tapeworm, an intestinal worm called Dipylidium caninum, when animals (or people) ingest them. This worm causes itching in the anus and if you look we can observe its presence in the feces, with an appearance similar to the cucumber nuggets placed in a row.
