advice re sedation for kitten on long trip

[Kerry MacKenzie]

Hi all I don't know if this will go thru because I'm having a lot of problems. But I have to try, as someone I know is driving in the next couple of days from Chicago to NY City and asked my advice about sedating her kitten for the trip. I believe the kitten is 5 months old, and certainly under a year. I've never used any sort of sedation and said i wd ask you wonderful guys. I believe Benadryl was mentioned recently on the list?  Any advice much appreciated! Kerry
