The necessity for insulation in a baby mammal's habitat during cold weather is vital for maintaining their body temperature and overall health. Insulation that maintains warmth while allowing for ventilation is crucial because it prevents the buildup of moisture and reduces the risk of excessive heat loss or hypothermia. Proper ventilation ensures that the habitat does not become stale or overloaded with humidity, which can lead to respiratory issues or promote the growth of harmful bacteria or mold.

Using materials that only absorb moisture would trap humidity in the environment, potentially causing discomfort and health risks for the young animals. Heavy blankets can provide warmth but might not offer resilience against cold drafts or moisture retention in the long term. Non-breathable materials could initially retain heat, but they would also create a sealed environment where air cannot circulate, increasing the chances of overheating and respiratory problems. Thus, the right type of insulation must balance warmth and airflow for optimal safety and comfort.
