Litter?

Hi all, wasn't sure whereabouts I should post this topic so health seemed to be the closest one and most related :) Would this litter be alright to use for a ferreets litter tray? I intend to use the same corner styled litter box my rabbit uses- she is very well trained :) I know some may ahve concern for the mixing of rabbit and ferret however I do not intend to let them roam free at the same time as I know ferrets have instinctual hunting instincts, although there may be exceptions I don't intend to risk this so my bunny and ferret won't be roaming the house at the same time :) https://www.amazon.co.uk/gp/product/B00JKCCWS2/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1 It's an all natural litter made up of compacted hay, would this be alright? I know ferrets aren't meant to consume plant matter, however I doubt a ferret consuming any other type of litter would be beneficial either? Unless I used shredded paper? Thanks all, Georgia :)

It should be fine but a ferret has a mind of its own so anything is possible with them.
