Hi,

     I planned to visit my family but one of my cats was sick in the car.
She had her mouth open like a dog and she was kind of hissing..  She had a
lot of saliva.  I went back home.  As soon as we were home, she behaves like
nothing had happened.  She was no more sick.  What happened?  It was not
hot.  My other cat was just fine.  Is there a way to prevent it from
happening again?

            Thanks,
