Best Cat Wormer for 2020

In the UK, there are eight types of common feline intestinal worms, although most can be grouped as either tapeworm or roundworm.

It can be difficult to diagnose pets with these parasites, especially if you have a cat who does most of their toilet business outdoors, and who indeed spends most of their time outside too. But there are a few telltale signs to always look out for.

Keeping your cat protected against worms is essential, as is finding a good product to tackle any current infestations. Below are our picks of the best cat wormers, as well as our guide on how to find the one for you and your kitty.

    Drontal Cat Wormer

    A veterinary strength solution for the treatment of round and tapeworms in cats, which should be recommended by your vet in the first instance of the appearance of these worms.

    It is the top-selling product here in the UK but is non-prescription, so really is the best way to tackle worms and prevent them from appearing again.

    They contain Praziquantel 20mg and Pyrantel Embonate 230mg and should be administered orally straight to your cat or mixed in with food. It can be given every three months to keep the worms at bay, or after 14 days to tackle a particularly bad case at that time.

    You should start to see the medication work within a day or two, so it is quick to act if there is a current infestation which needs to be ended.

    Panacur Wormer Granules

    Cats are notoriously crafty creatures. They know whether that roll of ham is to reward good behaviour, or whether it is to hide some medication.

    So, these granules, which contain the active ingredient Fenbendazole, are perfect for adding to food and ensuring they remain unaware. They’re virtually tasteless, so great mixed in with strong wet foods such as fish.

    They are effective against major tapeworm and roundworm species including Toxocara (which can cause problems if accidentally transmitted to humans). All this, without causing any harm or difference to your pet.

    You can buy a sachet dependent on your cat’s size, but this makes it easy to portion out. It can be used to treat lungworm, or else act as a routine worming treatment every month.

    Features

    • Easy to mix into food
    • Dependent on weight - easy to dose

    Specifications

    • Format: Granules
    • Worms: Tapeworm, Roundworm
    • Duration: 3 Months

    5.
    Beaphar Worming Syrup

    Kittens can become infected with worms through their mother’s milk, and even if there are no signs of worms, you should assume it is going to happen and prepare ahead.

    This syrup is not only easy for them to digest but is also chocolate flavoured to make it a bit more appealing to young tastebuds. It is a multiuse product, suitable for treating both the kittens and mothers without the need for separate products.

    It isn’t just for mums and babies, though – some older cats don’t like tablets, and need something more gentle. The syrup comes in a pump dispenser, so it can be issued directly into the mouth or mixed with food.

    Features

    • Great for young or old cats
    • Tasty flavour

    Specifications

    • Format: Liquid
    • Worms: Roundworms
    • Duration: Every 2 Weeks

    Prazitel Worming Tablets

    Has your cat definitely got intestinal worms, but you don’t want to spend multiple weeks administering treatment to them?

    This tablet is a single dose wormer, effective on all forms of worm straight away. You use one tablet per 10kg of weight, so you should only need between half a tablet and a whole one. They are round and scored down the middle so are easy to break.

    It will treat mixed infections of nematodes and cestodes, including Ascarids, Hookworms, Whipworms and Tapeworm. They can be given directly or into food, and the ability to break them into smaller pieces can make them easier to disguise.

    You can use it on kittens over 6 weeks of age, and every month as a preventative. Each tablet can also be shared between cats if you have several and need to split one tablet in half.

    Features

    • Good monthly protection
    • Easy to break into smaller pieces

    Specifications

    • Format: Tablet
    • Worms: Hookworm, Tapeworm, Roundworm

    Dronspot Spot-On Cat Worming Treatment

    This is the first spot on wormer to be sold outside the vets that cover every type of intestinal wormer commonly found in UK cats.

    It works fast to fight intestinal worms after just one application. A simple, single topical treatment can do the job, so there is no more fighting or having to disguise tablets or powders in food. It can be given to cats 0.5kg-8kg, and above 8 weeks of age, so is perfect to make the switch from kitten to adult wormer.

    This liquid will treat the animal for worms, killing any in the intestines. But it won’t prevent the animal from getting worms like a flea treatment prevents fleas, so you will need a separate product such as tablets for continuous protection every 3 months.

    Features

    • Non-oral
    • Easy to apply

    Specifications

    • Format: Topical
    • Worms: Roundworm, Tapeworm
    • Duration: Single Application

    • Flexible application
    • Good for multiple cats

    Bob Martin Clear Kitten and Cat Worming Tablets

    While there is no permanent treatment for worms, it is recommended to always look for any signs, and regularly protect your pet against them.

    A single dose of this medication will protect your cat for the next few months, and will also tackle any existing worms. You can use it on cats over 12 weeks of age, so it is a good second step towards protecting your cat in their adult life after their kitten formula.

    The dosage depends on their weight, and they are best given directly but can also be disguised in food.

    Features

    • Regular protection
    • For all adult cats

    Specifications

    • Format: Tablets
    • Worms: Tapeworm, Roundworm
    • Duration: 3-6 Months

    10.
    Droncit Spot On Worming Drops

    A vet-strength solution to fight tapeworm in cats.

    Each pack contains four tubes, with active ingredients including Praziquantel. As it is a topical treatment, it works via your cat’s blood to effectively tackle the worms wherever they are. It will also be easier for some people to apply, especially if your cat has an aversion to oral treatment.

    It only tackles tapeworm, and this will keep coming back unless a suitable flea treatment is also found. Keep around 48 hours in between dosing both flea and worm treatment.

    Unfortunately, there are very few roundworm-only medications out there, so this should only be used if your cat is definitely suffering from just tapeworm, and then suitable protection against both should be used from then on.

    Features

    • Easy application
    • Tackles tapeworm - good if you want to do everything separately

    Specifications

    • Format: Topical
    • Worms: Tapeworm
    • Duration: Single Application

    Buying Guide

    Types Of Wormers and Worming Treatment

    • Tablets – The best option. These can be given orally and directly for the best results, getting to work quickly and effectively. But they can also be mixed into food if broken up
    • Liquid – Good if mixed into food, say for younger or older cats. Varieties available, including undetectable liquid suspensions and tasty kitten syrups
    • Granules – Designed to be mixed into food, and is generally less detectable than liquids. They should be easy to digest and palatable
    • Topical/Spot-Ons – A relatively new way to fight worms, although they will usually only tackle existing infections rather than protecting against future ones

    Worm Prevention For Cats

    Some of the above will tackle existing infections, possibly needing a follow up after a few weeks to ensure the issue is gone.

    However, if you want to prevent worms from occurring, ensure you buy a medication which can do this. The best frequency is around every three months, but this may need to be more regular for any cats who pretty much live outdoors.

    Other Buyers Ask...

    Which worms do cats need to be protected against?

    The most common intestinal worms which will be a risk to cats in the UK are roundworms and tapeworms. Hookworms are another threat which they can develop from eating things such as eggs.

    Roundworms are mostly found in kittens. They can be infected from the mother’s milk it should be assumed that all kittens are infected and worming should be started at a young age. Kittens should be treated for roundworms every 2 weeks from 3 weeks of age until 8 weeks of age, then monthly to 6 months of age. The adult cats (greater than 6 months of age) should be treated every 1-3 months.

    Tapeworms are mostly found in older cats (unless a kitten has fleas). Treatment against roundworm and tapeworms should be used. Something which fights Dipylidium caninum should also be used on kittens who have fleas.

    Will the above kill tapeworms?

    Any medication which explicitly says it tackles tapeworms, whether alone or alongside roundworm, should do if you follow the correct dosage and for the correct duration.

    However, fleas serve as intermediate hosts for one common type of tapeworm, the Dipylidium caninum. Tapeworm infestation will reoccur even with the above treatments unless infestations of fleas are also brought under control.

    How often should I give my cat wormer?

    Your cat should be wormed around every three months if they do not spend more than an average amount of time outdoors, and do not hunt. This should be increased to every month for outdoor cats that hunt.

    Ask your vet if you are unsure – it may be best finding somewhere in between this guidance. If you do have to give them treatment more than every three months, ensure you purchase a wormer which can be used this often as some are strong so can only be used quarterly.
