why do cats pant

Cats pant primarily when they are trying to breathe in enough oxygen to meet their body's needs. Unlike dogs, cats do not usually pant to cool themselves, so panting in cats can be a sign of intense exercise, stress, overheating, severe pain, or an underlying medical issue such as heart disease, respiratory illness, anemia, asthma, or heatstroke. It can also occur due to anxiety or after strenuous activity. Persistent or excessive panting is often a cause for concern and may require veterinary attention, especially if accompanied by other symptoms like pale or abnormal-colored gums, collapse, coughing, or gagging.
