Best Cat Dewormer - How to Deworm Your Cat and Avoid Parasites?

Cat Dewormer

By playing outside, consuming infected prey, or even coming into contact with your shoes or clothing, your cat can catch parasitic worms at any time. As you will have understood, the risk of infestation of your cat by worms is permanent.

When your hairball is infested and not treated quickly, the worms can migrate from its digestive tract to other organs, creating lesions that can be fatal.

Fortunately, to avoid this critical scenario, it is sufficient toperiodically administer a good dewormer to your cat. To guide you in your choice of the ideal internal parasiticide, this article offers you some practical advice, as well as a selection of the best dewormers on the market.

Why deworm your cat?

The worms infesting the cat will settle in its body, feeding on its blood and its food. Over time, they can cause significant and irreversible damage to the cat's organs, which can cause death. Thus, the first reason why you must imperatively and regularly deworm your cat is to preserve his health.

In addition, most of these worms infesting cats are transmissible to humans, with serious consequences for their health. Indeed, some worms transmitted by cats can be found in your intestines, under your skin, in your eyes, and even in your liver!

So you must ensure the regular deworming of your little feline to protect you and your children from possible contamination.

Which dewormer for cats to choose and buy in pharmacies?

Dewormers and antiparasitics are easily found in online pharmacies, which is perfect when you know that neighborhood pharmacies do not stock this type of product. Moreover, this is why we necessarily added a link to an official pharmacy.

You will find 3 main forms of dewormer for cats on the market:

  • Tablet
  • products Pipette
  • products Syrup products

Tablets and syrups are for oral use and are very effective. Their only downside is that it can sometimes be difficult to administer them to the cat (but using the right technique it works fine).

Pipettes are for external use (are put on the skin of the neck of the cat) and are also very effective. However, they are still little used and few pharmaceutical companies manufacture really effective.

The recommended dose is 7 ml of product for each kilogram of the cat, administered twice, over 24 hours. For kittens, repeat the operation every 3 weeks.

Be careful not to confuse internal dewormer and external parasiticide

Note that there are two main families of antiparasitics for cats: internal antiparasitics or internal dewormers and external antiparasitics.

  • Internal dewormers are used to rid your hairball of parasites that have settled inside its body (usually intestinal worms).
  • External antiparasitics are used to eliminate all the parasites fixed on the skin of the cat, in particular fleas, ticks, lice or even chiggers.

Some internal dewormers can be applied externally, through the skin, in this case pipettes expressly designed for this, which can create real confusion.

Thus, to avoid any ambiguity, it is often recommended to opt for tablets, which reduce the risk of erroneous administration of the treatment.
