Cat Population Simulator

Explore hypothetical Hawaiʻi cat-population scenarios. These assumptions are not calibrated to a selected location.

Hawaiʻi location context

View mapped watershed and stream facts separately from population scenarios.

The legacy simulator remains an educational model with known demographic limitations documented in its archived audit. The location explorer does not fix those defects or calibrate the model. Results are not validated local forecasts or health advice.
