<p>Kennel cough is a common disease found in many different animals. The disease itself affects the upper respiratory systems of dog, cats, rabbits, pigs, and in rare cases it can affect humans. While some animals, such as cats, can carry this disease the majority of cases are found to involve animals that have been kept in close quarters for long periods of time. It is not uncommon for this disease to be found in animal shelters that house large numbers of stray and run-away animals. Kennel cough, also known as Bordetella, is common enough that the majority of animal hospitals and shelters will not accept an animal that has not been properly vaccinated.</p>
