Is it a scam to knock on the door and ask if you have seen a cat?

Not necessarily. Knocking on the door and asking if you have seen a cat may be a normal behavior to look for a pet, because many people will choose to look for a missing pet in their neighbor's house. However, there may be some scams. For example, someone may pretend to be a pet owner to defraud others of money or information.

In order to prevent being cheated, you can take the following measures:

1. If someone knocks at the door and asks if they have seen a cat, you can first ask about their identity and the characteristics of the cat to ensure that they are the real pet owners.

Don't disclose personal information or money information easily, especially to strangers.

If it is determined that this is a scam, it is best not to provide any help or information and report the case to the local police in time.

In short, knocking at the door and asking if you have seen a cat is not necessarily a scam, but we need to be vigilant to prevent being cheated.
