Persians, and other breeds with flat faces, are more prone to sneezing due to chemicals, product irritation, smoke or infection because of
their constricted nasal passages.
Your kitty's allergy to inhalants, food, bacteria or parasites can also cause him to snore as this condition may trigger a response in his autoimmune system — resulting in
constricted nasal passages.
Brachycephalic animals have a shortened muzzle which
constricts nasal passages and can result in respiratory and feeding problems.
