Why do some cats seem to get along with other cats? Their hormones offer a clue.
Despite a reputation for preferring to share space on their own terms, cats often live in groups. This behavior may seem contradictory, but new research suggests it’s a curious consequence of domestication — and biological factors can help explain why some felines may embrace their fellow cats more than others.
In a study published Wednesday in the journal PLOS ONE, scientists link displays of cat behavior to hormones and the gut microbiome. These elements shape interactions among cats and may explain how they tolerate cohabitation despite their solitary nature.
For example, the study found that cats with lower cortisol and testosterone levels were more tolerant of other cats and more willing to share food. Cats with higher levels of these hormones were less likely to interact with their fellow study participants. Meanwhile, cats with higher testosterone levels were also more likely to try to escape the room where they were observed.
Researchers at Azabu University in Japan conducted the study.
