Q. How old do kittens have to be before they can be dewormed?
JESSICA L DESROSIERS
A. Kittens can be dewormed as early as 2-3 weeks of age with an appropriate dewormed that is safe for use in kittens. They are then usually dewormed again about a month later to treat any reinfection or remaining worms that may be present. If worms are present, deworming the mother cat (if safe to do so) may also be needed.
The most common types of worms seen in cats and kittens are roundworms (long, spaghetti-like segments in the stool or vomit) and tapeworms (small, rice-grain like segments that break off separately and shed in the environment). As these two worms are treated differently, knowing which one is present is best for providing the right worming treatment. If you are unsure about the product to use or the type of worm, bringing in a sample to your vet can allow them to find and provide the correct and safe worming medication.
