Coughing is not an uncommon problem in cats; sometimes this may be a chronic problem where the cat coughs on a daily basis or it may be an acute illness associated with breathing difficulties. If your cat shows any signs of coughing with breathing difficulty, which may include open mouth-breathing, rapid breathing, wheezing or collapse you should contact your vet urgently. Sometimes coughing can be confused for vomiting hairballs, as cats often retch at the end of an episode of coughing. There are many causes of coughing and many of these can be treated successfully, so investigation and treatment by your vet is advisable. Many causes of coughing if left untreated, can progress over time causing severe consequences for your pet. If your cat develops a cough that does not get better after 2 weeks you should make an appointment to see your vet.
