They seem to be eating normally and their poohs are of normal shape, size and colour ranging from dark green to dark brown. I just thought they looked a bit odd around the middle section. They are active when i go near them and go to pick them up. But when I'm not too close they just move quietly about their hutch. I give them big bunches of green, leafy veges and as well as corn on the cub as treat, carrot, half tomato between the three every now and then sometimes snow peas, hay, capsicum, sometimes cucumber as a treat and one grape each as a really special treat like once a week. They drink water regularly I guess, never when I'm around but I do notice the water level going down throughout the day. Sometimes they just lie about and even stay still for a couple of seconds for a little pat then scamper away. I hope this helps.
