No Bunny Droppings / Urine
If the bunny stops urinating and pooing, then you should take it to the veterinarian. Lack of poo can suggest a blockage in the gut, perhaps a fur blockage, or some other material if your bunny eats cardboard or carpet or other indigestible things that can get caught in its guts. Bunnies die very quickly from blockages, so it is VERY important that you take your rabbit to the vet quickly.
