 This tactile action is combined with olfactory communication as the contact leaves scent from glands located around the mouth and cheeks.Cats also sometimes "head-bump" humans or other cats with the front part of the head; this action is referred to as "bunting".Again this communication might have an olfactory component as there are scent glands in this area of the body, and is possibly for seeking attention when the cat turns their head down or to the side while doing so.
