What causes aggression in hamsters, and how can it be managed?

Hamsters may exhibit aggression due to stress, fear, or territorial disputes. Ensuring they have a spacious, enriching habitat can reduce stress. Avoid sudden movements or loud noises around them. Handle your hamster gently and regularly to build trust. If aggression persists, consult a veterinarian to rule out health issues. Remember, some hamster species are more solitary and may prefer minimal handling.
