Leaving prey items inside the cage too long; I am probably the one who has you all confused about this subject. Sorry. For neonates, it is often nessecary to leave a food item in the cage over night. They must feel secure, and safe before they will eat. This translates to dark, and closed in for the snake. Thats the way they like it. Especialy at this age. I think i may have mis-spoken what I was trying to say before about not leaving food in too long. You had said that you left one in there for several days I think. And in my opinion, for what it's worth, that's not good. Overnight is O.K. but I personaly would not leave one in there any longer than that. I have never seen a snake eat anything which has been in the cage with it longer than that, and you don't need the bacteria which will build up. You are better off to throw that one away, wait till next evening, and put in a new one. When I said if he dosen't eat within ten or fifteen minutes, he won't,{i think that wuz me?}, What I meant was, that if a snake is ready to eat, it will usualy do so right away. Not always, but usualy. Most snakes that I have seen, will eat right away if they are hungry, and you give them what they want, how they want it. Some snakes, like baby drys are pickier than others, and it may take some patience and good advice to crack the code. But once you do, it will be o.k.
If he is going into shed, I'd say that may very well be the problem. Some of my snakes will eat no matter what time of the month it is; LOL But my indies will not eat when their eyes are cloudy, and they usualy stop feeding before there are any visible color changes at all. Many times they have refused to eat, and I would not no why, but then in a few days the eyes would turn blue, and I knew what was up. It seems that they know when they are getting ready to shed long before we do. Their bodies are going through changes that we cannot see.
Every time you pick that animal up, or even look in at it, you cause it to feel fear. That causes a LOT of stress for a tiny baby animal like that. My advice would be to set up the small cage, and absolutely leave it alone! Until after it sheds. Then brain a pinky, and try it. If that dosen't work, cmon back. Somebody here will know what to do. Hope this helps,
Tony.
