House rabbits that use a run outside sometimes

.. Do you put their litter tray out there?

Normally i do, but i didnt yesterday but they used their carry case as the litter tray :love;

I used to for Nutmeg as she wouldn't eat grass but now she does so I don't. Sometimes I might put a handful of hay out there, it depends on how long they are going to be out for, and I never bother with the lops cos they eat so much grass!
