   - Cat autonomously performs parabolic leaps onto window ledges, walks along them, sits, naps, and hops back down.
   - Dynamic surface tracking: If an underlying window moves or closes while the cat is resting on it, the cat wakes up and falls under gravity to the next surface or floor.
 
-- 🖥️ **Multi-Monitor Roaming & Elevation Navigation**:
-  - Full virtual desktop support spanning all connected displays with arbitrary resolutions, positions, and DPI.
-  - Automatically calculates distinct taskbar/work-area floors for each screen.
-  - Seamlessly handles elevation differences (e.g. stepping off higher floors into gravity falls, or leaping up steep monitor steps).
+- 🖥️ **Dynamic Multi-Monitor & Resolution Detection**:
+  - Full virtual desktop support spanning all connected displays with arbitrary resolutions, positions, and DPI scaling.
+  - **Live Hotplug Detection**: Listens to Win32 `WM_DISPLAYCHANGE` and `WM_SETTINGCHANGE` system events (with a 1.5s background check) to dynamically detect when monitors are connected, disconnected, rearranged, or when display resolution/scaling changes.
+  - Automatically recalculates screen bounds and taskbar floors in real-time, clamping the cat into valid active displays so it never gets stranded off-screen.
+  - Seamlessly navigates elevation differences between monitors (e.g. stepping off higher floors into gravity falls, or leaping up steep monitor steps).
 
 - 🪟 **High-Performance Transparent Overlay**:
   - Built with Win32 Layered Windows (`WS_EX_LAYERED | WS_EX_TOPMOST | WS_EX_TOOLWINDOW | WS_EX_NOACTIVATE`).
