Parasite Prevention and Indoor Cats

Before you decide that your indoor-only cat does not need parasite prevention, consider these important facts:


  • Cockroaches, mice and flies all can carry roundworm eggs. Cats are natural hunters and will hunt them!
  • 15 percent of commercial potting soil contains roundworm eggs.
  • The Northeast has the highest prevalence of roundworms than any other part of the country.
  • Other animals in the household that do go outside – like dogs and people – can bring in different parasites that can affect the indoor cat.
  • A study conducted in 2007 by the CDC proves that almost 14 percent of the U.S. population is infected with Toxocara (Roundworms) – much higher than what was originally thought.
  • The same study also states “Although most persons infected with Toxocara have no symptoms, the parasite is capable of causing blindness and other systemic illness.”
  • Children and immune-compromised people, such as cancer patients, people with HIV or AIDS and organ transplants, are more susceptible to infection with these parasites.
  • 40 percent of immune-compromised people have a pet at home.
  • Roundowrm, or Toxocara cati, are prolific egg producers and are estimated to produce as many as 24000 eggs per day
  • It is estimated that 3 million to 6 million people in the United States may be infected with Toxocar larva migrans each year.
  • In just 30 days, 25 female fleas can multiply to more than 250,000.
  • All it takes is one adult worm in a cat’s heart to be fatal. Cats that die from heartworm can be clinically normal one hour before death.
  • More than 25 percent of cats with proven heartworm infection, according to their owners, are kept indoors exclusively.
