I need help please!!  I just observed my 9 month old male kitten biting
my 6 year old spayed female cat at the scruff of the neck and almost
pinning her down!  I know that ever since he was a younger kitten he
would jump on her and chase her as if playing, but this really looked
like some sort of sexual thing?  It's really freaking me out because he
is neutered and I thought that would take care of these sort of things?

He is just about to be 9 months old.  Does this have something to do
with sexual maturity?  Will he ever stop?  The female is always so
contantly anxious around him...yet they can get along too.  The hair at
her neck is thinning out (might be because of him).

Please if anyone has any experience with something like this I will
take any advice I can get.

Thank You
Paige
