Separate dog or cat outcomes from mouse, human and mechanistic evidence.
Open evidence matrix →Healthspan is about daily function, not age at death alone.
The atlas starts with a pet and a change in daily function, then opens the evidence and cost layers only when they are useful.
Turn mobility, behavior, eating, body-condition or elimination changes into a structured record.
Use the observation planner →Read a direct answer, measurement boundary and evidence trail for healthspan conditions.
Browse healthspan conditions →Keep controlled outcomes, mechanisms, ongoing studies and product marketing in separate evidence states.
