Why do cats breathe through their mouths? - briefly
Cats may breathe through their mouths due to respiratory issues such as asthma or allergies, or when they are overheated and need to cool down quickly. In some cases, it could also indicate stress or anxiety.
Why do cats breathe through their mouths? - in detail
Cats, like many other mammals, are obligate nasal breathers, meaning they primarily breathe through their noses. However, there are certain situations when you might observe your cat breathing through its mouth. This behavior is not typical and usually indicates an underlying issue that requires attention.
One of the primary reasons cats breathe through their mouths is due to respiratory problems or obstructions in the nasal passages. If a cat has a blocked nose, it may be unable to draw air efficiently through its nostrils, leading it to resort to mouth breathing as an alternative. Common causes of nasal blockages include allergies, infections (such as feline upper respiratory infections), or the presence of foreign bodies like grass blades or small particles that have been inhaled.
Heat stress is another factor that can cause cats to breathe through their mouths. Cats do not sweat like humans do; instead, they rely on panting to cool down. When a cat becomes overheated, it will open its mouth and rapidly breathe in and out to increase the evaporation of moisture from its lungs and tongue, thus regulating its body temperature. This is similar to how dogs cope with heat, and it is a natural response to high temperatures or intense physical activity.
In some cases, dental issues can also lead cats to breathe through their mouths. Severe tooth decay, infections, or other oral health problems may cause discomfort, making it difficult for the cat to close its mouth properly. As a result, the cat might resort to breathing through its mouth to alleviate pain or avoid further irritation.
Additionally, certain medical conditions can affect a cat's ability to breathe normally through its nose. For instance, tumors or polyps in the nasal cavity can obstruct airflow, forcing the cat to breathe through its mouth. Neurological disorders that impact the nervous system responsible for controlling breathing patterns can also lead to this behavior.
It is essential to note that while occasional mouth breathing might not be cause for immediate concern, persistent or excessive mouth breathing should always prompt a visit to the veterinarian. A thorough examination and possibly diagnostic tests will help determine the underlying cause and appropriate treatment plan.
In summary, cats typically breathe through their noses, but they may resort to mouth breathing due to respiratory issues, heat stress, dental problems, or certain medical conditions. If you notice your cat breathing through its mouth frequently, it is advisable to consult a veterinarian to ensure there are no underlying health concerns that need attention.
