Great looking Jungle, on the whole feeding thing, the best advise I can give is to be PATIENT, I can't stress that enough...I know its very hard, and can be very frustrating switching over from Mice to Rats, but it can and will happen. I know many people say that thier snake is "Hooked" on mice, but I have switched over MANY "Hooked" snakes in the past, and really all it takes is patience....some take longer than others, but I have never had one of my snakes NOT switch over. It tends to be harder when you only have one snake, I have found it works best if you are able to thaw out rats and mice together...if not, try and snag a little sandwich bag of rat bedding from the local pet store...freeze it, and then use the bedding to scent the mice with.
From my expereince, during the time of "Switch Over" I tend to go longer periods of time between feedings, that ensures they are good and hungry when trying to switch. And as I mentioned, the key to the whole thing is Patience, it can and probably will be very frustrating, but the end result will be a really good thing, and it might take more than just a few times of trying, I had one hold out 5 months before finally making the switch over, luckly I had other snakes to feed the rats too, but now she feeds on rats like they where candy...I am actually working on a Jungle Carpet now that doesn't like rats...but it can be done.
