Hello kc6201,
Please don't tell cat owners that even a small amount of chocolate is okay to give their cats. Chocolate, even a small amount, can make a cat very sick. Chocolate should not be given to dogs either in any amount.
If she gets an occasional lick of something salty, don't worry about it, but stick to cat food and cooked meat.
She just licked one? lol. She'll be fine. Even things that are "toxic" to cats and dogs like chocolate they can eat in small quantities and usually be totally fine. I honestly never heard that salt is poisonous to them though. I just got a cat about a month ago. He likes licking the cheese flavoring off popcorn and chips. He's fine :)
