Do you guys know the type of cage for rabbits?The kind of metal cage with a pull-out tray that are used for catching droppings.Well I have that kind and I was thinking if I cover the floor with newspaper and wood shavings it should work as well, right? Was researching the net and the only say if it's wire floor then at least half of the floor must be covered with something to ensure the piggies don't get sore feet.What do you guys think?
