My kitten is very much into bunting he will run full steam ahead when he see's me to come say hello which is often accompanied by bunting licking and biting my nose.
I sometimes need to grap him by the scruff of the neck to get him to let go and then I put him on the floor and ignore him for a little while until he can return and cuddle nicely- sometimes needs to be repeated multiple times.
He also has a tendency to play rough and will Bite and scratch my arms and legs as though they are his prey saying no or yelping in pain doesn't seem to deter him and if I take him off he treats it like a game and comes back even harder. I know he's a kitten and mostly just wants to play and he does have toys to play with.
Overall he is extremely social and outgoing and loves attention I love him to bits but could do without the teeth marks.
