However, repeated or heavy drooling should always be observed carefully.
When Drooling During Sleep Can Be Normal

Some cats drool slightly when muscles relax deeply during sleep.

Head and mouth position may allow saliva to collect and drip.
3. Dreaming Phase
Cats may drool lightly during deeper sleep stages.
