I have a feeling my fridge is going to be way too cold - the rice I had for dinner was frozen solid when I took it out! I'll still test and see though, it may be a bit warmer towards the top.
I've been doing a bit of reading on this fridge method and I have seen that feeding is not to be expected while in there, not that he is doing much anyway! I also read about vomiting/pooing, which I hope he does either of soon- at least it shows something is working inside him!
I'll let you all know how it goes.
