cat heartworm

Cat heartworm is an internal parasite that causes significant lung damage. Cats become infected by being bitten by mosquitoes. A mosquito injects these worms into the body of the cat, and it migrates toward the lungs.

Heart conditions can vary among cats, but the most common among Domestic Shorthair cats is adult-onset hypertrophic cardiomyopathy (HCM), enlargement of the heart muscle. This condition can cause the heart to beat faster, slower, or with an irregular rhythm and can lead to heart failure.

Several symptoms can indicate heart failure, including open-mouthed, labored or rapid breathing, and lethargy. There is no known cure for this condition, but there are treatments available, so a proper diagnosis is necessary to keep your pet stable.
