The facts about heartworms

  • Heartworm is a blood-borne parasite spread by mosquitoes

    Carried in the blood, heartworm transmission can be as simple as a single bite from a mosquito having previously fed on another infected animal.

  • The threat across Australia is highest in tropical and coastal regions

    With our warm Australian climate, mosquitoes can plague us all year round. Known to breed in greater numbers around areas with stagnant water - from ponds and streams to yards and household plants - mosquitoes can also travel great distances when blown by strong winds.

  • Both indoor and outdoor cats are at risk

    While flyscreens can help limit the entry of mosquitoes into our homes, those persistant little pests invariably find a way inside, leaving indoor cats at risk.

  • Heartworm is a silent killer with few symptoms

    Taking up to 6 months to mature into adults, and living up to 2-3 years within a cat, heartworms may cause very few symptoms until it's too late.

  • There is no approved treatment, only preventatives

    Currently there are no approved treatments for eliminating heartworm from infected cats, making prevention the best.

Spread with a single bite from a mosquito carrying blood with infective larvae, the transfer is simple yet devastatingly effective. These nasty invaders are often hard to spot until it's too late, and can result in life-threatening respiratory diseases even at an immature stage of development.

The risks of leaving your cat untreated
