Mortimer's Christmas manger

The beginning was absolutely wonderful, even though I don't understand why he would need to tug all the figures out and how sleeping in manger would be warm and cozy... but then... he becomes Christian, and moves into a better house... er... uh... no.
It would have been a better story if the family had noticed him sleeping in the manger and got him a cage with a lots of things to do and climb and have fun and food and water and everything a little mouse needs, and he would have been happy there, because as it is now, he'll be homeless in about a week. Thank you, Jesus.
