Here's why:
* Limited sweat glands: Opossums have very limited sweat glands, making it difficult for them to cool down effectively in extreme heat.
* Thick fur: Their dense fur coat, while beneficial in colder weather, traps heat and can lead to overheating in hot environments.
* Nocturnal habits: Opossums are primarily nocturnal, which helps them avoid the hottest parts of the day. However, if temperatures remain high at night, they may still struggle with the heat.
Signs of overheating in opossums:
* Panting
* Excessive salivation
* Lethargy
* Weakness
* Seizures
If you see an opossum showing signs of overheating, it's important to provide shade and access to water. You can also try to cool them down by misting them with water. If the opossum is severely distressed, it's best to contact a wildlife rehabilitator.
Overall, opossums are more at home in temperate climates with moderate temperatures.
