I used the clip on water bowls from the cat carry boxes on my cratesm gives some more space and stops them treading in it making more mess, my other comment would be a lot less litter in the tray, as its a sod to clean up and gets every where, also I use a hooded bed takes up less space than the blanket and gives more cage space
Its usually about 6 7 weeks cage rest when this type of things happen
