I had a bunny rabbit who had to be given regular doses of dilute pineapple juice because of internal blockages. It seems to help. I can't see why it would be bad for a mousie (I've had many, many little mousie friends in my lifetime). How old is your mousie? They don't actually live all that long, as animals go. :( bonni
