A one-month-old Pennsylvania baby is hospitalized after she was attacked by three family pet ferrets and sustained severe facial injuries.

According to WPVI, sources have said that the incident took place on Thursday in the child’s Darby Borough home.

The mother of the infant allegedly placed the child in her car seat in the downstairs home and then went to the upstairs of the home. In that time, the three pet ferrets got out of their cage, attacked the baby girl and chewed her face.

The parents’ heard the child’s cries and found the ferrets attacking her. The baby was transported to a Children’s hospital. She lost 25 percent of her face in the attack.

Her four siblings have been removed from the home and are now in the custody of child services.

This is not the first time a ferret attacking and severely injuring an infant has made the news. As KCTV noted, a four-month-old Missouri infant lost seven fingers when a pet ferret attacked him in 2011.

The parents of that baby told authorities that they were asleep when the attack happened and once the father found out what the animal had done, he killed it. Prosecutors, however, said that no one was at the home with the child at the time of the attack.

Each parent received probation in that case and the child is living with a relative.
