Why are pigeons such filthy animals?
<|assistant|>
Pigeons are filthy animals due to their habit of gathering and storing food items in their nests and flocking together in overcrowded areas, which leads to the buildup of feces, mites and other harmful parasites. They are also known to feed on garbage and excrement, resulting in a dirty and smelly environment.
