Trusted protection

Your cat trusts you to do the right thing. And that means protecting your cat from dangerous parasites with Interceptor® (milbemycin oxime), trusted by veterinarians for more than 25 years.1

Protection is key

Just one easy-to-give dose of Interceptor® (milbemycin oxime) administered monthly provides protection against three dangerous (and potentially fatal) infections:

  • Prevents heartworm disease caused by Dirofilaria immitis
  • Protects against intestinal parasites:
    • hookworm (Ancylostoma tubaeforme)
    • roundworm (Toxocara cati)

Why choose Interceptor®?

There are no approved treatments for heartworms in cats, so it’s vital to provide your cat with protection. By giving your cat Interceptor every month, you’ll help to eliminate the risk of heartworm disease.
Other important points to remember:

  • If there are dogs diagnosed with heartworms in your area, then your cat is at risk.
  • Make sure that you protect all the animals in your home from heartworm disease.
  • A single adult heartworm can be fatal to a cat2
  • More than 25% of confirmed feline heartworm cases occur in cats residing entirely indoors.3
  • Even 1 missed dose can leave your pet highly susceptible to disease caused by parasites.

Serious threats to your cat

In addition to heartworms, intestinal parasites can also pose a serious risk to your cat. Interceptor® is labeled to remove both hookworms* and roundworms+– two dangerous types of parasites for your cat.


  • A common parasite of cats, prevalence can be as high as 20%4
  • Infection occurs via ingestion of larvae from a contaminated environment, from larval penetration of the skin, and/or ingestion of infected hosts4
  • As voracious bloodsuckers, hookworms can cause anemia, diarrhea, and weight loss in kittens4
  • An infection with large numbers of worms can be fatal4


  • Another common parasite of cats, prevalence can be as high as 20.3%5
  • Infection occurs via ingestion of infective eggs from a contaminated environment and ingestion of infected hosts6
  • In cats, infection can cause ill thrift, a pot-bellied appearance and vomiting6
