Yes I replace the hay everyday, Max knocks over the hay feeder everyday I need to get a hay feeder and litter tray built in, I put the meadow hay in the litter tray as I’ve noticed he doesn’t like the feeding hay on his litter box, what he has started doing I pooing all round the edge of the litter tray, someone told me that he maybe trying to tell Lily that this is his toilet and for her to use the other one.
