Cat Why deworm my cat?

by admin

Deworming is an act of health for both the animal and the human environment, especially if there are children in contact with the animal. Indeed, worms are dangerous because they can cause significant lesions on the internal organs of the cat and other types of worms can be transmissible (and therefore potentially dangerous) to humans: these are the organs that first undergo these worms because they do not have the same hygiene as adults. As the symptoms are often undetectable, it is not easy to tell if the cat is infected or not because the eggs of the worms pass mainly in the stool.


What types of worms can we find?

It simply consists of giving the cat one: this product will kill the worm in the animal’s digestive tract.

There are 2 types of worms, namely roundworms or nematodes (roundworms) and cestode worms (tapeworms, known as tapeworms).


There are in fact 3 categories which are roundworms 10 cm long and which will mainly infect kittens, causing diarrhea, bloating and reduced immunity. They are caught through the placenta or breast milk.

The 2nd category includes hookworms which are more dangerous and rare worms because they cause high fever and digestive problems. Contamination occurs through breast milk and the larvae penetrate the kitten’s skin.
Finally, whipworms are worms that are frequently found and encyst the large intestine.


The best known and most widespread is the tapeworm, also called Dipylidium, of which we find visible traces in the stool in the form of scattered grains of rice. This type of worm causes irritation and nutritional deficiencies. It is mainly transmitted by the chip.

Other parasites exist such as:
– Microbes or protozoa including giardia which binds to the mucous membrane of the small intestine and causes progressive weight loss and also coccidia which also parasitize the digestive system of cats.
– External parasites, recognizable by sight as fleas which cause an intense scratching, grooming and licking reflex, favoring the ingestion of hairballs. There are also ticks which are transmitted only when the cat is outside a habitat, they often attach themselves around the neck and ears and can cause inflammatory reactions. Ear mites is one of the existing parasites in kittens: it settles in the ear canal of the cat and causes painful ear infections. The symptoms are the presence of blackish, fragrant earwax and the fact that the cat rubs the ear very frequently. Finally, ringworm is a small fungus which eats away at the hair at the base: the symptoms are blackness of the skin and the hairs which fall out, in particular on the level of the head.

The possible risks

For the man :

Eggs and larvae are present in the faeces of contaminated animals and accidental contamination of humans and children in addition is always possible when they play in a sandbox, for example.
The symptoms are then visible such as fever, fatigue, possible growth disorders.

For the cat:

Symptoms and risks depend on the cat’s age, health and degree of infestation. Even if the symptoms are not always characteristic of a particular type of worm, it is recommended whatever happens, in case of doubt, to deworm the cat with a product which will act on all digestive worms.

However, we find common symptoms like eggs or larvae in the feces, some anemia, diarrhea, a dull coat, a bloated stomach, a decrease in vitality.
Once these symptoms have occurred, the contamination is very present: the risks of lesions in the digestive tract are then numerous and can lead to a general deterioration in the state of health of the cat.
Other worms feed by absorbing the blood of animals or the food contained in the digestive tract and this can have serious repercussions, sometimes fatal in cats.

If in doubt, do not hesitate to ask your veterinarian who will know which dewormer to turn to to properly and effectively treat the parasite.
For example, for the treatment of fleas in cats, it is also necessary to treat the cat and its direct environment with an insecticidal liquid product, either by spray or by mist. For ticks, the veterinarian can turn to a total acaricide which will eliminate the ticks without any pain. For ear mites, the treatment is done in 2 stages, first by cleaning the cat’s ears with a moistened compression and then by prescribing the acaricide prescribed by the veterinarian. Finally, for ringworm, the treatment is done using a fungicide administered orally or by bath.
As can be seen, the treatments for deworming cats differ depending on the type of parasite and other factors that must be taken into consideration.

Which products to use?

There are different ways of administering dewormer to a cat, namely:
. dewormer in pipette: very effective against roundworms and flatworms because the solution is contained in the pipette and is applied directly to the cat’s skin, at the base of its neck.
. deworming tablets: it exists flavored with meat to facilitate its ingestion, so the drug is placed in the cat’s bowl, mixed or not with its food or then can be offered as a treat.
. dewormer paste: it is a paste in applicator to deworm especially lactating cats. We are going to put this paste on the cat’s tongue, which will swallow it gently. You can also mix this deworming paste with your food.

The veterinarian will know what dose of dewormer to prescribe to the cat, taking into consideration the cat’s weight and age. But to optimize the intake of dewormer, it is strongly recommended to change the litter regularly and to clean its tray as well as all potential sources of infestation.

Treatment frequencies

All dewormers are curative and they work when you take them. They are in no way preventive and that is why it is advisable to deworm your cat regularly (every 6 months to once a year) to avoid any physical and physiological decrease, any decrease in immunity. Kittens should be dewormed every two weeks before the age of 3 months and once a month until they are 6 months old.
The kitten must be dewormed from the age of 6 weeks because it may have been contaminated in utero by the placenta if the mother is also contaminated. Breast milk can be a cause of contamination.
For an adult cat, it takes about 2 to 4 sessions per year.
For breeding cats, it is necessary to deworm 2 to 3 days before mating and 15 days before and 3 weeks after giving birth.
Let us repeat that it is very important to deworm your cat regularly even if it does not show signs of contamination. Indeed, the symptoms begin to appear only when the cat is strongly contaminated.

Be careful, if you have several cats, it is important to deworm them all at the same time.

For all these reasons and because the health of your cat is as important for him as for his owner, it is essential to monitor his animal because the symptoms are often very discreet and can still have serious repercussions.
