🌡️ Which hamster substrate actually stays coolest?
Rather than guessing, I decided to test it.
I left a range of common hamster substrates in a warm room for four hours before measuring their temperatures to see which stayed coolest.
I tested:
🐹 Hay
🌿 Aspen
🪵 Beech chips
🥥 Coco chips
🌰 Cork granules
🌱 Soil
🏖️ Sand
The results genuinely surprised me!
Cooling substrates won't replace good husbandry, but they can give your hamster somewhere naturally cooler to sit, groom and relax during warm weather.
Have you noticed your hamster choosing one area of their enclosure more than others when it's hot? ☀️
