       <tr><td><strong>Soil moisture</strong></td><td>Water saturation of the top 1 cm of soil as a percentage. Above 40% indicates saturated ground; below 20% is dry. Useful for assessing whether ground is workable, and for motorhome or caravan pitch suitability.</td></tr>
       <tr><td><strong>Concrete °C</strong></td><td>Estimated temperature of sun-exposed urban paving. Concrete absorbs more solar energy than grass and cannot cool itself through evaporation — surface temps can run 15–25 °C above air temperature on sunny days. See <a href="./temperatures.html">derived temperatures</a>.</td></tr>
       <tr><td><strong>Vehicle °C</strong></td><td>Estimated ambient cabin temperature inside a sealed, parked vehicle — adjusted for your chosen vehicle type. Values above 35 °C are dangerous for children and pets; above 45 °C potentially fatal within minutes. See <a href="./temperatures.html">derived temperatures</a>.</td></tr>
-      <tr><td><strong>Indoors °C</strong></td><td>Estimated temperature inside a building with windows closed and no active cooling. Select your building type from the dropdown — brick, modern insulated, Victorian terrace, stone cottage, timber frame, top-floor flat, or conservatory. Indoor peak typically lags the outdoor peak by 2–4 hours due to thermal mass.</td></tr>
+      <tr><td><strong>Indoors °C</strong></td><td>Estimated temperature inside a building with windows closed and no active cooling. Select your building type from the dropdown — brick, modern insulated, Victorian terrace, stone cottage, timber frame, top-floor flat, conservatory, or office block. Indoor peak typically lags the outdoor peak by 2–4 hours due to thermal mass.</td></tr>
       <tr><td><strong>Managed °C</strong></td><td>The same building model with two interventions: curtains closed by day to block solar gain, and windows opened whenever outdoor air is cooler than inside — the standard UK heatwave advice. Toggle with the Managed tick next to the building dropdown.</td></tr>
+      <tr><td><strong>Fur Temp °C</strong></td><td>Estimated fur surface temperature a cat or small dog experiences in direct sun, calibrated for a thin/short coat. Choose your pet's fur colour — Black/Dark, Brown/Tabby, Golden/Tan, or White/Pale — from the dropdown; darker coats absorb more solar heat and run hotter.</td></tr>
+      <tr><td><strong>Paw Temp °C</strong></td><td>Estimated ground/pavement surface temperature for paw contact, colour-coded by burn risk: green below 40 °C (safe), amber 40–52 °C (discomfort or possible burn on prolonged contact), red above 52 °C (can burn within 60 seconds). If you can't hold the back of your hand on the surface for 7 seconds, it's too hot to walk your pet.</td></tr>
+      <tr><td><strong>Pet Shade °C</strong></td><td>Shaded air temperature for a resting pet, using the same shade estimate as Shade Air but with a lower, pet-specific alert threshold — small pets have far less capacity to dump heat than humans.</td></tr>
+      <tr><td><strong>Pet Home °C</strong></td><td>Indoor temperature estimate for a pet left home alone, using the same model as the Indoors column but with a lower, pet-specific alert threshold (26 °C) rather than the human heatwave guidance threshold.</td></tr>
       <tr><td><strong>Visibility km</strong></td><td>Horizontal visibility in kilometres, sourced from the Copernicus CAMS air quality model. Below 1 km indicates fog or very thick haze; below 10 km suggests mist, smoke, or significant pollution. Relevant for driving, flying, cycling, and photography.</td></tr>
       <tr><td><strong>AQI</strong></td><td>European Air Quality Index (0–100+), combining PM2.5, PM10, ozone, nitrogen dioxide, and sulphur dioxide. 0–20 = Good; 20–40 = Fair; 40–60 = Moderate; 60–80 = Poor; 80–100 = Very Poor; 100+ = Extremely Poor. Sourced from Copernicus CAMS.</td></tr>
       <tr><td><strong>Pollen</strong></td><td>Pollen concentration in grains per cubic metre for the selected pollen type — choose from total, grass, birch, alder, mugwort, olive, or ragweed via the dropdown. Sourced from the Copernicus CAMS pollen forecast. Low = &lt;10; Moderate = 10–50; High = 50–200; Very High = 200+.</td></tr>
