Dewormers for Cats and Kittens

Your cat may look perfect on the outside, but worms may be silently causing harm on the inside. Worms in adult cats can cause mild to moderate digestive symptoms, including vomiting, diarrhea and gas. Kittens are commonly born with worms or exposed to them at a very young age. If left untreated, worms can lead to more severe digestive symptoms from malnutrition to weight loss and restricted growth. It is important to keep your cat or kitten free of worms for their health and well-being but also because some types can be transmitted to humans.

FAQS About Cat and Kitten Dewormers

Petco carries over-the-counter dewormers for cats and kittens, and prescription medication can be filled online at Petco through the Express Scripts pharmacy.

Consult your veterinarian for a treatment plan and time frame. Generally, the first dose will kill the adult worms present at the time of dosing. Many treatment plans will require subsequent doses that will likely need to be given to kill the adults that were larvae when the first dose was given.

Consult your veterinarian on the treatment plan for your kitten. Since kittens are highly susceptible to parasites, it is recommended by the Companion Animal Parasite Council that kittens begin a deworming treatment starting at 2 weeks of age. Additional doses should be given every 2 weeks until 2 months of age, then monthly until 6 months of age, and quarterly thereafter.

Not every dewormer works for all the worms cats can carry. Therefore, the best dewormer varies depending on the type of worm that your cat has been infected with and your cat. Consult your veterinarian for the best cat dewormer treatment plan.
