In Portland (Oregon) the Police received a terrified call from a family besieged in their bedroom by their pet cat, Lux. Lux had apparently scratched the baby, for which she was spanked. Lux took umbrage at this and attacked the family, the members of which (including the dog) were forced to take refuge in the bedroom.
The matter was resolved in due course and Lux is now back with her family. She has a history of aggressive behavior. I have to ask if it is wise to keep a cat like Lux in a house with a baby. I'm not sure I would like her in a house with me.
