Looking for a mouse in the grass

Yesterday afternoon Rascal was looking for a mouse in the yard grass.   The irrigation line reached this part of the yard so that is why the grass looks good and is tall.

Here is a 16 second video of Rascal:  https://youtu.be/aF5MJmF-nW8

Then last night I left the door partially open as I was too tired to get up-and-down to let Rascal in-and-out during the night.  This morning I found the remnants of an eaten mouse in the hall outside my bedroom.
