Hungry rats attack sleeping people
Incidents of rat attacks are extremely rare in everyday practice
A rat has recently attacked a little baby in the city of Tver, Central Russia. When the baby-girl was sleeping alone in the room, a rat attacked the child and started biting her furiously in the face. The little girl was hospitalized as a result of the incident - doctors of the local hospital managed to save the child's life, although the girl had to stay in the reanimation department of the hospital for quite a long time.
