Does she have foragers? Mine love the buffet balls, you can get them cage mounted, hanging and loose. I stuff them with shredded paper and treats.
Also the wheel forager that goes on the side of the cage. In fact mine like any sort of foragers but it is best to start easy and work your way up. I always show them how to do it at first and then let them try. Some are smarter than others
Then I like to keep a rotation of shredding toys, for mine thats the wooden ones as they demolish them! Any big wooden toys, hanging ones, ladders etc. I do try and avoid ones with rope or string and any that have them i remove it or trim it right back if I can't remove it and keep a close eye.
Have you seen the java toys? They do the hanging roots which mine enjoy. Also the ones that look like 4 ladders out together to form a square - can't remember the name of them? They arent cheap and they are quite big but mine have one of those each aswell and I hang toys inside of the middle to make it more interesting for them.
Then there's the hanging coconut one that mine love, also stuff these with hidden treats.
You can get the little forager boxes or the 'finger traps' ones and hide treats in those. Or you can use clean cardboard, eggboxes are a good choice, and make your own. Also you can cut up cardboard and thread it to make a hanging shredder yourself.
If they are destroying their toys they must be enjoying them
though it can be difficult to find ones that last more than 5 minutes!
