 Cats have been shown to be able to recognize human emotions through smell, with fear being more strongly detected than other emotions. This suggests that cats can interpret the emotional state of humans based on sense alone. Additionally, cats showed increased stress when exposed to fear odus, indicating that they are capable of interpreting the emotional content of these odus. Finally, it was observed that cats preferentially used their right nostrils when reacting to fear odus, suggesting that the left side of the brain is responsible for processing emotional information from oda.
