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.

Feline miliary dermatitis is a skin condition that typically results from an underlying allergic reaction, most commonly to fleabites. An affected cat will have a very itchy rash and may lick, bite, and scratch at the affected skin, quickly progressing to small lesions with scabs on them. The offending allergen must be removed for long-term resolution.

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.

Ringworm infections in cats are caused by a fungus, not a worm. They can be easily recognized, though definitive testing by fungal culture is recommended. Ringworm is highly contagious and can be spread between animals and from animals to people. The clinical signs, diagnosis, treatment, and risks are explained in this handout.

Roundworms are one of the most common intestinal parasites observed in cats. Almost all cats will become infected with roundworms at some point in their life, most often as kittens. Roundworms are not particularly harmful to adult cats, but large numbers may cause life-threatening problems in kittens and debilitated older cats. Roundworms can also be transmitted to humans. Diagnostic testing, treatment, and preventive measures are explained in this handout.

If a negative reaction occurs, please call your veterinary office.

Tapeworms are parasites that infect the gastrointestinal tract of cats, other animals, and humans. Several types of tapeworms are known to infect pets, but the most common species observed in cats is Dipylidium caninum, which is transmitted through fleas. Risk factors, clinical signs, treatment, and prevention are explained in this handout. Other, less common types of tapeworms that affect cats and humans are also covered.
