Species
Domestic cat
Highly individual vocal repertoires make cats the clearest demonstration of why a per-animal baseline matters more than a species-level average.

Capture note
Purring fundamentals sit around 25–50 Hz and are usually below what a phone microphone reproduces cleanly; purr detection relies on the amplitude-modulation envelope rather than the fundamental.

Body-language channels
Only these are weighed for this species.
Limitations
- • Adult cats direct most vocalisation at humans rather than at each other, so meow interpretation is heavily individual.
- • Purring accompanies both contentment and pain, and cannot be read as positive on its own.
