One of my buns has regularly started leaving uneaten cecotropes. It started a couple of months ago that if he had even one treat (yoghurty drop things) or more than a smidge of veg there would be one or two the next morning. So i cut those out. Now every couple of days there are still some uneaten ones. He's fed a shot glass full of pellets each day and plenty of hay, nothing else. He weighs 1.6 kg and has been on a diet to get this down a bit. Any ideas? Other than this he is eating, drinking, pooing, playing fine.
