We have this problem with some of our buns while others never get any stuck to them. One thing I did with a couple of our problem children is to cut down on the leafy greens. We use unscented babywipes to clean them off.
Benjamin had a couple of issues of this. I just set him on the sink and gently poured water over his bottom and cleaned him that way. Could be one of the greens are not agreeing with him. Cut back a bit and give him more hay for awhile. With the gi statis you don't want to deprive him completely of greens.Is the wire on the bottom of his cage so that the poo will not drop through at all or do you have a litter box. Could be he is sitting in it and getting it smeared on his bum that way.
yep, that's one possibility. He has a litter box on the wire and i think he may have just gotten it smeared. And we had a bunch of people over today and it was kidna stressing. They say stress can cause such issues. As of now, his pooping is fine, and I haven't seen more cecals smearing on him! *YAY!*
