you dont really need to change his water everyday. just make sure he has soom. he needs to be left alone for a week or two! like I said before they can go along time without food. and if he is going into shed he probably wont eat any way. my wont. to let you know when I got my bp she was about 1 yr old. the guy I got her from told me she only ate 3x in a year for him so you see they can go along time without food. she eats well for me 1 mouse 2x a week. and she has grown almost 7 inches and more than doubled her weight in 5 months. so the best thing to do right now is just leave him alone for a while and then start to handle a little at a time. if his eyes are blue and cloudy lookin or he looks real dull he is prpbably going into shed and you just really need to leave him alone . also there is some good info on this web site in the care sheets check them out it will really help and good luck!
