Felix used to be an everyday cat, just working her day job keeping mice at bay at Huddersfield Station in West Yorkshire, England.
She was brought in by First TransPennine Express at only nine weeks old to help take control of the pests in the station and she really grew into the role.
After five years of hard work she finally got the promotion she deserves.
No longer is she a simple mouse catcher - she is now Senior Pest Controller, complete with the adorable visibility jacket, name tag and authority that goes with the title.
