How do you know if a hamster has broken leg or another just bit its leg?

There are a few signs that may indicate that a hamster has a broken leg or has been bitten by another hamster:

1. Limping: If a hamster is limping or favoring one leg, it could be a sign of a broken leg or injury.

2. Swelling: Swelling around the leg or foot could also indicate a broken bone or other injury.

3. Pain: If a hamster is in pain, it may vocalize when you touch its leg or try to move it.

4. Bleeding: If there is bleeding from the leg, it could be a sign of a bite wound or other injury.

5. Difficulty moving: A hamster with a broken leg or other injury may have difficulty moving around or climbing.

6. Behavior changes: If a hamster is normally active and playful but suddenly becomes lethargic or withdrawn, it could be a sign of an injury or illness.

If you suspect that your hamster has a broken leg or other injury, it's important to take it to a veterinarian as soon as possible for evaluation and treatment. The veterinarian will be able to determine the cause of the injury and provide appropriate care.

In the meantime, you can help your hamster by keeping it in a quiet, safe place, away from other pets. Provide plenty of food and water, and avoid handling the hamster too much to minimize any further stress or injury.
