My 1 year old male cat has been introduced to my male kitten about 7 weeks. He is always meowing around it and then bites his neck and goes behind him. The kitten wants to run to the cat and the cat gets scared sometimes. when I separated them, my adult cat constantly meows for the kitten. and when the kitten meows he meows back and goes on a search. Is he trying to kill him or something! Its sort of this weird obsession, this is the first day they are meeting
