Just like humans, cats can develop allergies to things in the environment. Cat allergies can be caused by many different things, and the cause usually has to be figured out by a process of elimination. Sneezing that's caused by an allergy is often accompanied by scratching and other skin problems. These include frequent rubbing of the face and excessive grooming which may cause hair loss.
Some triggers of reverse sneezing are rapid eating or drinking, exercise intolerance, pulling on the leash and excitement. It's possible that sinusitis and other respiratory disorders cause episodes. This condition is more common in small dogs, although any breed can experience it. Short-faced breeds such as Bulldogs, Boxers, Pugs, Boston Terriers and Shih Tzus are more prone to reverse sneezing.
