First, it is possible that cats are born with a narrow nasal cavity, so it is more difficult for them to breathe than other cats. In this case, you can choose to do nasal surgery, enlarge the nasal passage, and make breathing smoother.

Second, it may be because the cat has a cold and its nose is blocked, so it breathes heavily. In this case, it is recommended that the owner take it to the hospital for anti-inflammatory treatment in time.

Third, it may be caused by virus infection, especially herpes virus infection, which may cause thick nose. This situation requires antiviral treatment and anti-inflammatory treatment.

Generally, blue cats have shallow breathing sounds. If the breathing sounds become heavier, first observe whether there are secretions, sneezing, coughing, etc. If there is, you should consider catching a cold; If there are still tears, increased gums, runny nose and so on. Consider whether you are infected with herpes, mycoplasma and chlamydia virus; If the blue cat just has a stuffy nose and even affects breathing, you can take pictures to check whether there is any foreign body in the nasal cavity.
