Heartworm Disease

Do Cats Get Heartworm?

The answer is an unequivocal YES, but the feline situation is vastly different from the canine situation.  While it is not true that the feline infection is not as common as the canine infection, the feline infection has recently been found to be a much more widespread problem than previously believed. The incidence of feline heartworm infection rivals or surpasses that of feline leukemia virus or feline immunodeficiency virus. An incidence of 2% to 14% of all cats has been reported for endemic areas, making heartworm a concern for any cat living where there are mosquitoes.
