My boyfriend and I have an indoor cat. He is 1 year old and his name is Spock. He is normally very sweet and loving. He is rarely home alone because we have opposite schedules and one of us is usually here with him. He has recently started having negative habits only with me. I work from home part of the time and he has this cute habit of standing up on his back legs and literally tapping me on the arm or shoulder when he wants attention:
Just like this, which is cute. I stop and give him attention for a while and then I'll set him down out of my lap and he will spin around and bite me. He has done it several times. But when he does the tapping thing to my boyfriend he never bites him. When I told my boyfriend, he almost didn't believe me but then he saw him do it.
Why would he only bite me, and what should I do to stop this behavior?
