This article is super interesting for two reasons. One, the complexity of olfactory social cues in many animals is fascinating and seems to create a world of sentience and awareness that we have very little access to. Two, it shows (once again) that rats, an unfairly maligned creature, are capable of great care for others, as are many other social species.
“How do animals that help their brethren manage to prioritize those most in need? A new study shows that rats can use odor cues alone to determine how urgently to provide food assistance to other rats in need.”
