How Long Does It Take for the Deworming in Cats to Take Effect?
As a cat parent, you probably need to know how long will the worm medicine take to work on cats. Will the effect be instant or not?
Usually, the waiting game can take up to 3 days to 3 weeks. The deworming medication can take only days to effect, but it might take longer to work entirely with more severe cases and infections.
Also, certain factors can help determine how long a dewormer takes to work in kittens and adult cats. The time can depend highly on the type of worm and medication.
Depending on the type of worm
Worms are parasitic nightmares that live within a cat’s body and make them ill. If left unaddressed or untreated for too long, they can, unfortunately, be fatal. As a pet owner, there are three types of parasitic worms you should be aware of:
The time needed to expel hookworms mostly depends on the dewormer medication. Using a dewormer with Fenbendazole, a common ingredient for hookworm medication, can take 3-5 days to fully eradicate the worms.
Through treatment, tapeworms can easily and quickly be treated with dewormers. After proper deworming treatment, these worms should be eliminated after three days.
Roundworms can take longer to eliminate. These parasitic worms tend to be more resistant and stubborn against dewormers. At most, it might take 3 weeks for full resolution.
Depending on the type of dewormer used
Aside from worm type, another thing to note is the dewormer medication used on your cat.
Worms are eradicated by various dewormer medications, each with its level of effectiveness on a particular worm species. The dewormer type will significantly affect the outcome and results of the treatment.
To give you better insight, here is a table detailing which medications are effective for certain worms! Note that these are active ingredients and not the brand itself.
|Praziquantel||Not effective||It takes 1-2 hours to take effect, 2-3 days to be visibly noticeable, and 3-9 days to resolve.||Not effective|
|It takes 1-2 days to take effect after treatment and 3-9 days to be resolved.||Not effective||It takes 1-2 days to take effect after treatment and 3-9 days to be resolved.|
|Fenbendazole||3-5 consecutive days of treatment. Some may need a 2nd treatment.||Only effective for specific tapeworm types.||3-5 consecutive days of treatment. Some may need a 2nd treatment.|
|Pyrantel pamoate||Need 2-3 treatments, typically set 2-4 weeks apart.||Not effective||Need 2-3 treatments, typically set 2-4 weeks apart|
Knowing what was used can help tell you how fast a dewormer works. Just note that certain deworming medications are explicitly made for certain types of parasitic worms.
For tapeworms, praziquantel and fenbendazole seem the most effective. The former medication treats taenia and dipylidium, while fenbendazole is recommended primarily for taenia tapeworms.
Now, how long does tapeworm medicine take to work in cats? The answer varies, though they usually take effect after three days.
On the other hand, Roundworms require more aggressive dewormer medication and may need a few extra doses for complete eradication. The most common medication ingredient are fenbendazole, milbemycin, moxidectin, and pyrantel.
Lastly, hookworms are most commonly treated with fenbendazole, which is given to cats for 3-5 days to ensure that all worms are expelled.
Also, note that if a cat died after deworming, a possible reason could be overdosing. Remember that overdosing on deworming medication is highly toxic to cats.
Factors Affecting the Time It Takes for Dewormers to Work in Cats
Aside from type of worms and medication, a couple of other factors can affect the period of deworming a kitten or adult cat. Usually, it varies from cat to cat.
With common infections, getting your cat entirely worm-free can take about three days. For severe cases, it can take longer.
See below the factors that can affect how long a cat’s deworming process is!
1. Number of worms
The number of parasitic worms in your cat’s body can majorly affect the duration it takes for the deworming to kick in. Cats with severe infections will take longer for the worms to leave their systems altogether.
Some cats may even need a few doses to eradicate the worms.
2. Resistance to medication
Unfortunately, some worms are resistant to certain types of medications. If the cat still has worms after deworming, it will likely need a follow-up course of dewormer medication to eliminate the worm situation.
Though, how do i know if dewormer is working on cat, you might wonder. You will know if the medication is running its course if you see many dead or dying worms in your cat’s feces.
