Cats + Parasites

  • 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.

  • In North America, many parasitic lungworms infect cats. Cats can become infected by swallowing infective stages of parasitic lungworm. The exact means of becoming infected varies according to the life cycle of the particular parasite. Signs can include coughing, heavy breathing, wheezing, sneezing, poor appetite or anorexia, weight loss, fever, enlarged lymph nodes, and ocular or nasal discharge, and may be more prominent in kittens due to their immature immune systems. Although the success rate of treatment depends on the severity of symptoms and the number of parasites present, the prognosis for recovery is generally good.

  • Moxidectin and fluralaner are combined in one topical treatment for use in cats. Moxidectin topical is an avermectin antiparasitic that is used to prevent heartworms and treat intestinal parasites (hookworms and roundworms). Fluralaner is used to treat and prevent fleas and also kills black-legged ticks (deer ticks). Give as directed. Side effects are uncommon but may include hair loss at the application site, itching, vomiting, diarrhea, lethargy, excessive drooling, and dry skin. Moxidectin + fluralaner should not be used in pets that are hypersensitive or allergic to it. Do not use this medication in sick, debilitated, or underweight cats. Use caution in cats with known neurologic disorders. If you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately. If they are not available, follow their directions in contacting an emergency facility.

  • Moxidectin is an avermectin antiparasitic that is used to prevent heartworms and treat intestinal parasites. Imidacloprid treats and prevents fleas. These two drugs are combined in one topical product for use in cats, dogs, and ferrets. Use as directed. Side effects are uncommon and usually short-lived, however, if you suspect an overdose or an adverse reaction to the medication, call your veterinary office immediately.

  • Selamectin + sarolaner is used topically on the skin to treat various parasites, both on and off-label, 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. It should be used with caution in sick or underweight cats. If a negative reaction occurs, please call your veterinary office.

  • Whipworms are intestinal parasites measuring about 1/4 inch (6 mm) in length. They live in the intestinal tract of cats where they can cause severe irritation. Whipworm infection results in watery diarrhea, weight loss, and general debilitation. Fecal testing will not detect every infection. Whipworm infection in cats is rare in North America but cases appear to be rising.
