Why are pigeons such filthy animals?
<|assistant|>
Pigeons are filthy animals because they do not take care of themselves. Many of the actions they take, such as lack of personal grooming and nest building, create a unsanitary living environment that leads to the spread of disease and illness. Furthermore, many of the parasites and diseases that pigeons can be carriers of are potentially very dangerous to human health, so their fecal matter can potentially cause serious harm.
