  • Your mouth is warm

Cats love warm places, especially during winter. So if it starts smelling your mouth and laying on top of it, they are after your body heat. By smelling, your cat detects whether there’s warm air coming out of your mouth. And since it’s located right next to your nose, it becomes a convenient ‘heater’, so to speak.

This is the same reason why your cat will often sleep on your face. It’s not that they are trying to smother you to death. Your breath is just warm and comfy to the feeling.

  • You ate something smelly

One of the main reasons why cats sniff your breath is because it smells something yummy. It’s possible that you just ate a steak or a pizza.

Your cat will climb to your face and try to sniff your breath because it detects a delicious smell. It will also appear that your kitty is smelling your breath when, in fact, it’s smelling the last food you ate.

Sometimes, your cat will try to peck your mouth to taste what you ate. Also, if you’ve been vaping, your cat might get attracted to the scent that has attached to your nose. Even after vaping, your breath will still smell the flavor of the vape juice.

Some experts suggest that cats have the ability to sense changes in our physiological processes, including sickness.

This will make your cat smell your own mouth because of the changes in your unique scent.
