Can keeping a cat cause bronchitis?

Keeping a cat may potentially cause bronchitis.

Microscopic particles or allergens may be present in a cat's fur, skin secretions, urine, saliva, and dander. When inhaled by humans, these substances may trigger allergic reactions leading to bronchitis symptoms such as coughing and asthma. Particularly for individuals who are allergic to cats or have weakened immune systems, keeping a cat may increase the risk of developing bronchitis.

In addition, if the living environment of the cat is not properly maintained—for example, if the litter box is not cleaned regularly or the cat is not bathed and groomed frequently—this may increase the indoor concentration of bacteria, viruses, and allergens, thereby raising the likelihood of developing bronchitis and other respiratory diseases.

Therefore, for individuals who are prone to allergies, it is advisable to avoid keeping cats or to take appropriate protective measures to reduce the risk of bronchitis. At the same time, if bronchitis symptoms have already appeared, prompt medical attention and treatment are recommended.
