Many cat owners will have experienced their cat jumping up onto their lap and headbutting them straight in the face. If a human did this we may think they were trying to attack us, but don’t worry. With cats they are doing something totally different.

Pheromones are chemicals that are secreted outside the body and can affect the behaviour of other animals. Cats produce lots of pheromones in glands around their face which they use to mark things they come in contact with. It is thought that cats do this to claim certain things as their property/territory such as their favourite human.
The head butting (also known as “bunting”) behaviour can also be taken as a sign of love. Both domestic cats and wild cats (like lions) will face rub and headbutt with cats they know well. They also do it to members of their pride as a way to mark each other as family and show affection. You should feel honored if your cat headbutts you as it’s cat language for “Hey, you, you’re in my gang.”
