<human>: Can you give me a shortened version of the text?

I have a female cat about 10 months old and for the most part she is an extremely social cat with people.  She doesn't mind being picked up or handled and only shows her disapproval vocally.  This weekend I'm watching a friend's cat - a slightly older male - of which they have spent a few weeks with before.  Sammie, my cat, has been litteraly sulking in corners, meowing and groaning everytime I come near her or pick her up as well as hissing at the other cat.  Nothing other than vocal interaction has taken place and it seems more like a cautionary warning rather than a threatened response.  Is time the only remedy for this?  I feel as if I have a three year old who didn't get what they wanted for their birthday and is being forced to apologize for their rudeness against their will.
<bot>: Temper Tantrum cat - all vocal, physically passive (no clawing or biting at all).  Just wait it out and not give her attention?
