A cat bites your nose when it feels relaxed. It's a way to show affection and is commonly referred to as 'love bites' by pet parents.
Usually, a cat bites your nose when they feel very relaxed or when you are petting them. Some cats also bite your hair.
This is a normal part of their grooming routine. It's a way to transfer their scent and make you a part of their territory.
Your cat's nose has many olfactory glands, which help them smell. They can detect odors from your breath, and even from other cat's scents on you.
When a cat is excited or feeling anxious, they may be trying to vent their feelings by nipping your nose. They will also bite their nose when they're playing with you.
If you're in the middle of a very exciting game of fetch with your cat, you might notice them biting your nose. It is not aggressive behavior, but it can cause a lot of irritation to your pet.
Adults might bite their snout to scent mark you or if they aren't getting enough attention from their humans.
Kittens can also nibble their nose during play, because it is a way to express themselves and get your attention. This is a crucial period to teach them social etiquette and what behavior is acceptable during this phase of development.
To stop this behavior, blow air into their face every time they try to bite your nose. This will disorient them and will eventually teach them that your nose is not a good place to be bitten.
