My wife and I recently adopted a stray kitten into our house.  She's
about 12 weeks now and was probably about 8 when we found her.  We're
having a problem with her attacking us and biting at us.  It seems to
mostly be play because she never has her hair standing up or hisses
when she does it but it can be very annoying.  At first, we were very
confused because sometimes she would be the sweetest cat ever, purring
and letting us hold her and pet her and then other times she would
scratch us and meow when we hold her and try to get down.  However, we
think we've singled out the problem to one situation.  Basically, if
it's just one of us in the house with the cat she'll be very sweet, but
if we're both in the house she'll act rambuctious.  Does anybody have
any suggestions?  Thanks.
