This is not necessarily true. Snoring may also occur in light sleep. Cats with special facial structures will have heavy breathing sounds when they are not sleeping. Generally, sleeping cats will have a weakened response to external stimulation. They usually wake up with the slightest noise, but they may not react at this time.

Tips:

Cats sleep most of the day, and most of the sleep time is in light sleep. Parents should not disturb the cat when it is asleep.
