Study suggests a cat’s purr may be more revealing than its meow

Version 1

Researchers at the Museum für Naturkunde Berlin and the University of Naples Federico II report that a cat’s purr may be a more reliable acoustic fingerprint than its meow. In the study, published in Scientific Reports, the team analyzed recordings from 27 domestic cats collected in Berlin households and shelters, then compared domestic-cat meows with archived vocalizations from five wild felid species. They found purrs carried stronger individual signatures, while meows varied much more by context, especially in domestic cats, supporting the idea that domestication and life with humans favored more flexible meowing.

Why it matters: For veterinary professionals, the findings add nuance to how feline vocal behavior is interpreted in clinic, shelter, and behavior settings. The paper reinforces that meows may reflect situational arousal, solicitation, or human-directed communication more than stable identity, while purrs, although often affiliative, shouldn’t automatically be read as contentment because prior literature shows cats also purr during stress, pain, labor, and near death. In practice, that means vocalizations still need to be read alongside body language, context, and the individual cat’s baseline behavior. (nature.com)

What to watch: Expect follow-up work on whether these acoustic signatures can improve feline welfare monitoring, shelter assessment, or even automated tools that help decode cat-human communication. (scientificamerican.com)
