What are roundworms in cats?

Feline roundworms are intestinal parasites. They are the most common type of intestinal worm in cats in Australia. The adult worms live in the small intestine. There are two species of roundworms that can infest cats in Australia: Toxocara cati and Toxascaris leonina.

How do cats get roundworms?

Cats become infested with roundworm by ingesting infective eggs from a contaminated environment (e.g., the back yard or other outdoor area) or through eating an infested host such as a bird or rodent.

Protecting cats against roundworm is essential, not only for your cat’s health, but also the health of you and your family. If roundworm eggs are accidentally ingested by a human, the parasite can migrate to internal organs, affecting muscles, eyes and the brain. Young children are considered most at risk as they are more likely to play in contaminated areas and place things in their mouths.

Monthly deworming of cats is recommended to reduce environmental contamination with roundworm eggs and minimise the risk of transmission to people.

Monthly treatment with NexGard SPECTRA® protects cats against intestinal worms, including roundworms, as well as fleas, ticks, mites, heartworm and lungworm.
