Cats sticking out their tongues and panting like dogs may be caused by overheating, strenuous exercise, heart disease, stress response, etc. The cause needs to be confirmed based on the cat's specific situation, and then targeted treatment can be carried out. If it is caused by overheating, stress reaction, or strenuous exercise, cats can generally relieve it on their own; if it is not caused by external stimulation, it is best to take the cat to a pet hospital for examination and treatment.
