People seem to forget that 4 or 5 weeks is NOTHING, I have animals that take 8 weeks and the tree is no need for action.
Feeding is also not linked to defecation because the animal does not defecate does not mean it should not be fed.
As for warm bath it is in most cases complitely unecessary, unless the animal has a persistant bulge near the cloaca there is no need to intervene.
Bottom line they go when they are ready.
