What people are saying about coats and grooming is probably correct, but it’s worth noting that these animals are actually often “full of dirt”. If you dig out earthworms they will have lumps of dirt stuck to them. Many animals with fur and feathers purposefully put fine dirt into their coats (I’m not sure why exactly, I think it protects from parasites and sun somehow).
