Biting plastic litter box

She has plenty of wood chew toys and she just started to chew her plastic litter box. Should I intervene?

she could be bored of her wood toys. Make sure it's not JUST wood toys. throw in some plastic baby keys, or put some treats in a cardboard tube and fold down the ends (to keep her entertained) also, try rotating the toys, different toys each day!
it looked like she ate some (i could be wrong)make sure she doesn't bite of junks and eat it.
you could put some cardboard there (i put cardboard around my bunny's litter box, it helps keep the hay in the litter box)
