Fortunately, this makes it more difficult for heartworms to affect the larger organs, but can create significant heart, pulmonary artery, and respiratory problems. While it is less likely cats will get heartworm, this doesn’t mean it can’t happen. Studies indicate that a solid approximation would be 10%; so, for every 100 dogs that are heartworm positive, there will be 10 positive cases of feline heartworm.
