Any way to stop a kitten from chewing plastic?

My girl Bunny is 6 months old and has found a keen interest in chewing things; mostly cardboard and soft plastic. We weren’t too concerned about this until she took a silicone thumb cover off of a nintendo controller and ate it (which we didn’t actually realised happened until she threw it back up). I’m worried she’ll end up swallowing something that is more harmful.

Are there any chew toys on the market that would be safe for her? i’m thinking maybe a puppy toy but wanted to ask if anyone had suggestions. Thanks!
