Homeowners in the Dallas-Fort Worth area got quite a surprise when they checked out the video on their doorbell camera.

A very polite cow had sauntered up to the house and onto the from porch, peered into the front door and nudged the doorbell, the Houston Chronicle reported.

It happened in the suburb of Mansfield, the Chronicle reported.

After waiting on the porch for a few minutes, the cow turned and walked away.

It’s unclear where it came from and where it went after ringing the family’s doorbell.
