Cat head-butting happens a lot. It is scent exchange and friendship reinforcement. I believe this is the hardest domestic cat head-butt on YouTube! Therefore it is the hardest. If someone can disprove that statement, I’d be pleased.
The cat is Titan – an F1 Savannah. This short video is an extract from an earlier video. The person is Kathrin Stucki of A1 Savannahs who raised Titan. That is why Titan is so close to her. The voice you first hear is the human caretaker of Titan. I have forgotten his name, sorry. They are in a large pet shop, warehouse facility in the USA.
Titan stopped everyone who walked by him, which is bound to happen because he is so impressive. He has a sweet, boyish voice. His “owner” calls him manly. Yes, he is, but he is also quite young and more a big boy than a man (without anthropomorphizing cats). He certainly gives you a belt when he shows his friendship.
