Some cats are born with congenital abnormalities that cause breathing problems. Few cats suffer from cardiomyopathies, that is, heart muscle problems that causes respiration problems. There are a few cat breeds that are genetically prone to bronchitis, asthma or allergies. Asthma is caused due to breathing in cigarette smoke, dust, pollution in air like pollen grains, dust, food allergies, etc. An infected mosquito bite may lead to heartworm disease. This causes chronic respiratory disease and even lead to death of the cat.
