Cats + Parasites

  • The ear mite is a surface mite that lives on cats, dogs, rabbits, and ferrets. It is usually found in the ear canal but it can also live on the skin surface. Mites are barely visible to the naked eye. Clinical signs of infestation vary in severity and may include ear irritation, leading to scratching at the ears or head shaking, dark waxy or crusty discharge from the ear, areas of hair loss resulting from self-trauma, a crusted rash around or in the ear, and an aural hematoma. Your veterinarian will advise you about which insecticidal products are suitable. Your veterinarian may want to re-examine your pet to ensure that the mites have been eliminated after the initial treatment has been performed.

  • Heartworm Disease in Cats

    El gusano del corazón es un parásito de la sangre llamado Dirofilaria immitis que reside en el corazón o en los grandes vasos sanguíneos de los animales infectados.

  • Esafoxolaner + eprinomectin + praziquantel is given topically on the skin to treat and protect against various internal and external parasites and prevent heartworm in cats. Side effects are rare but may include hair loss at the application site, gastrointestinal upset, skin reactions, or neurologic signs. Use caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

  • Demodicosis is a parasitic skin condition caused by Demodex mites. These microscopic mites can be found on the skin of all animals but, in some cases, they multiply to excessive levels and cause clinical signs. Signs vary depending on the species of mite involved, though generally involve hair loss, skin inflammation, and crusting. Demodex mites found on cats and dogs do not spread to humans.

  • Fleas are the most common nuisance and parasite affecting cats, and an infestation can lead to serious health problems. Flea control requires a three-pronged approach; they need to be eliminated from 1) your cat, 2) any other cats and dogs that you have, 3) your home and yard. There are many flea control products available and your veterinarian can help you determine which are safest and most effective for your pets.

  • Fluralaner is given by mouth or applied topically and is used to treat flea and tick infestations, and also off-label to treat certain types of mange and mites. Give as directed. Side effects are uncommon but may include stomach upset or neurologic symptoms. Do not use in pets with a history of seizures. If a negative reaction occurs, please call the veterinary office.

  • Giardiasis is an intestinal infection caused by a microscopic protozoan. The parasites attach themselves to the intestinal wall and the damage causes an acute, sudden onset of foul-smelling diarrhea. Diagnosis may be by routine fecal flotation or presumptively based on clinical signs. Fenbendazole and metronidazole are the drugs most commonly used to kill Giardia. Giardiasis is the most common intestinal parasitic infection of man and can potentially be passed from cats to humans.

  • Harvest mites, also known as red bugs, trombiculid mites, scrub-itch mites, berry bugs or, in their larval stage as chiggers, are mites that are commonly found in forests and grasslands. Harvest mites are relatives of spiders.

  • Heartworms (Dirofilaria immitis) are blood-borne parasites that reside in the heart or nearby large blood vessels of infected animals. Recent studies of cats with heart and respiratory diseases have found an incidence of heartworms that is far greater than previously thought. Veterinarians now strongly recommend that all cats receive year-round monthly heartworm preventives. There are excellent heartworm preventives now available for cats, making prevention of heartworm disease safe and easy.

  • Heartworms are blood-borne parasites that reside in the heart or adjacent large blood vessels of infected animals. There is no drug approved for treating heartworms in cats and surgical removal is generally the best option. Veterinarians now strongly recommend that all cats receive year-round monthly heartworm preventative in areas where mosquitoes are active all year round. Cats that live in colder areas, where mosquitoes are seasonal, should be given monthly preventives for at least six months of the year.
