Ah right. I would still say the cage could do with more enrichment though, not just cramming toys in but by making it more interesting. For example if she won't burrow then try placing underground tunnels and cardboard hides in yourself. Different levels can make a difference too, as well as providing shelter underneath.
Hopefully others have more suggestions. Just remember it isn't uncommon for syrians to find something 800 square inches in size too small though so don't feel bad. Some don't settle until they're in something double the size of that after no amount of cage enrichment improvement have helped, you just have to do what you can
