Kel - rescue remedy is like homeopathic drops that you get in spray from a health food store.
Also available from pharmacy and also in drops. You can add it to water to drink if you don't want the spray.

Or in my case, I add a few drops to the blankets in my cat cages before the cats travel Works a treat!

I have a friend who said she used to get MASSIVE panic attacks after the breakup of her marriage, and rescue remedy helped her immensely. It's only about $13 and seems to be worth a billion times its weight in gold.
