I don't even know how I could leave mine, took me almost a year to get him to trust me to change his water bowl and food bowls. He was so neglected, I think the previous owner fed him through a door at the bowls and his water was a hamster bottle hanging out of his cage. That was the first thing I got rid of, it was full of brown nasty water. Yes I got bit, but with patience, and learning his behavior, I would give him his warm broccoli in the evening,can't bite with a mouth full of food and taught I him to scoot over, and then I could reach in and get his food and water bowls. Our night time routine is I dim my table lamp and he swings. I worry that a change in this routine would set him back. I did take him with me when I first got him and he was a champ. I just might do that. The family is planning on a beach trip.
