10 Best Cat Dewormers 2026 in the United States

Elanco Drontal Broad Spectrum Dewormer, 50 Tablets, is designed to combat multiple types of parasites – specifically tapeworms, roundworms, and hookworms – making it a versatile choice for cat owners. This product is suitable for cats and kittens over 1 month old and weighing at least 1.5 pounds. The dosing is straightforward: one tablet per 4-8 pounds of body weight, which can be administered directly by mouth or mixed with a small amount of food, adding to its ease of use.

Given that it is effective against a wide range of parasites, it reduces the need for multiple deworming products, which is convenient for comprehensive parasite control in a single treatment regimen. The product comes in a package of 50 tablets, making it a good option for households with multiple cats or for long-term use. Some cats might resist taking tablets, and owners might find it challenging to administer the correct dosage.

It is suitable for cats of all breed sizes and life stages. The compact size of the bottle (2.5 x 1.5 x 1.75 inches) ensures easy storage. For those looking for an effective, broad-spectrum dewormer, Elanco Drontal offers a reliable solution, although it is always prudent to monitor for any adverse reactions and consult with a veterinarian as needed.

The Safe-Guard (Fenbendazole) Dewormer Liquid is an oral dewormer that takes care of a variety of parasites including stomach worms, lungworms, hookworms, and nodular worms. This wide spectrum of targeted parasites makes it a versatile choice for cat owners. The liquid form can be convenient for those who find it challenging to give their cats pills.

However, it's important to note that this product is primarily labeled for cattle and goats, which may raise concerns about its specific efficacy and safety for cats. It’s advisable to use this dewormer under the guidance of a veterinarian to ensure it’s appropriate for your cat’s particular needs and to avoid any potential side effects. The product doesn’t give clear guidelines on the age and weight range for cats, so again, professional advice is crucial. The frequency of treatment isn't specified, which might require further clarification from a vet.

Administration should be relatively straightforward since it’s a liquid, but some cats may still resist. But given its primary use for livestock, careful consideration and professional consultation are essential before using it for cats.

This liquid cat and kitten dewormer contains pyrantel pamoate and is designed to remove common intestinal parasites like roundworms and hookworms. It comes in a 3.4 oz (100 ml) bottle with a butterscotch flavor, which helps make administration easier since many cats accept the taste without fuss. The liquid form allows for precise dosing based on your cat's weight, especially for cats under 10 pounds, with a recommended dose of 5 ml per day. Unlike some treatments, you don't need to withhold food before or after giving it, which adds convenience.

The product targets the main worms cats often get, making it suitable for routine parasite control in both kittens and adult cats. It is primarily effective against roundworms and hookworms, so if your cat has other types of parasites, this might not cover them. Side effects are generally mild with pyrantel pamoate, but as with any medication, some cats could experience minor digestive upset. You should always monitor your pet after dosing.

A mild downside is that this product is sometimes marketed for both cats and dogs, so always double-check the dosage and ensure you’re using the correct amount for your cat’s size. This liquid dewormer is a practical choice for cat owners looking for an easy-to-administer, flavored treatment for common worms in smaller cats and kittens. It is straightforward to give and covers important parasites, though it may not be a one-stop solution for all worm types.
