There's just something not quite right about Dillon. When he's being normal, he's so mischeivous etc but since getting his new hutch he's just gone really really quiet. He sleeps all the time, even in the evening now. I can't see that his appetite has been affected. I leave all the doors open for him as he normally will just lay out on the rug in the lounge. Plus, he's loving attention and nose rubs and normally he wont let me near him. Should I be concerned?
