Ive had a problem with bunny and Benji peeing in the corner of there run. I tried blocking it off but they just peed as close to the corner as they could, I put a digging tray there which was just used as a litter tray and attracting flys. So today I got rid of the dirt tray and lifted the run up to give it a reallly good clean. Well the stench that came from the part I cant normally get to was awful!!! I dont know what to do so for now Ive put a different run there, one which has a metal bottom so fingers crossed ill be able to spray it down regularly rather than let it build up in places I couldnt see like the other run!
