Why does my rat eat his droppings?
Rats do not usually practice eating their droppings (in some animals, like rabbits, this is an essential part of digestion), but when they or other animals do this, it is ooften a sign that the animal isn’t getting all the nutrients he needs in his diet. Try changing his diet to rodent blocks (sometimes sold as “rat and mose pellets” or “critter cubes”) and see if more fresh vegatables in the diet can help. You may also want to try a hamster multivitamin added to the water supply.
