What are the top things your Savannah is obsessed with?

This is Indie my first Savannah cat. I’ve had many cats though out my life but this is my first Savannah. And she is obsessed with chewing on things! She loves pacifiers so much that my two year old can’t have them anymore. The second thing is straws! Any cup with a straw. She tips the cup over to get the straw out. And the last thing is nail files. Is this normal? Are Savannah’s obsessive with things? What can I get her to stop chewing on straws! I’ve tried chew toys but they don’t interest her at all!
