The cat is normal but has a blocked nose. It may be caused by secretions in the nasal cavity, nasal stenosis, or respiratory infection. If the cat often suffers from this condition, it is best to take the cat to the pet hospital for examination to avoid delaying the condition. It is best not to frighten cats or exercise excessively, especially short-nosed cats. At the same time, pay attention to the hygiene of the cat's nasal cavity and clean up any foreign matter in time.
