Hamster fell about 1 meter, now has red-purple skin under nose, a little blood at mouth, energetic but trembles and breathes rapidly at times
Expert Answer
A hamster trembling and breathing rapidly after an injury may be frightened or may have suffered internal injuries. When a hamster falls from a height, the chance of internal injury is relatively high. It is recommended to take the hamster to a veterinary hospital for examination promptly and adopt corresponding treatment based on the results.
If the hamster is only frightened or unable to move due to pain, you can appropriately give it some anti-inflammatory and pain-relief medication and provide adequate nutrition, while keeping its environment quiet to help it recover as soon as possible.
