gravol, Rescue remedy or Cocculine
 

Anyone ever use Gravol, rescue remedy or cocculine on their pets, perferably with cats. Does RR or Cocculine make them sleepy? pros/cons of each? it will be used for flying in cabin on plane. Thanks

I've used Rescue Remedy myself. It's awesome. It doesn't seem to calm the dog down much, but it doesn't work for all of them.
Try it in advance if you want to know how it will affect your cat. Careful with gravol. Not sure how much you'd give a cat.
I gave Scruffy half a gravol and he went bonkers. Kind of the opposite of what I was going for.
