Catnip

Catnip was a herb which grew in Katie's garden. It was used in spells such as Cat's Tongue. Catnip was one of Solomon's favourite things. (Katie and the Cat who Talked)

"Catnip!" was also a word used in a magic spell which Katie used to speak to the Beast of Bodmin. (Katie and the Big Cat) "Catnip" was the password to Katie's diary, the writing on which was invisible until the password was spoken. (Katie and the Witch's Swap)

Doreen's shop, The Magic Lantern, sold catnip. (Katie and the Cat Swap)
