Yes, a piece of furniture in front of the bathroom door is NOT a good thing for an old lady with a weak bladder [I would have to wear diapers!

Get the tiels used to going into the cage at night by putting their dinner in it and closing the door once it's dark. If you start ten days to a week before you need it for the window replacement, it should work out just fine.
