This is the amusing moment a pet cat was seen struggling to squeeze through a glass door to enter an office.

Ratiwut Ruangroong spotted Dam Rongphak, the black feline, pawing at the glass and forcing himself into a narrow gap at the Khok Samrong Police Station in Lopburi, Thailand.

Footage shows the five-year-old kitty wriggling his body through the opening after failing to push the heavy door panels apart on December 15.

After successfully making it inside, Dam Rongphak approached Ratiwut, seemingly asking for some attention.

Ratiwut said: 'We gave Dam Rongphak the 'position' of Public Relations Officer and Receptionist because he often wanders around the building and lounges in the lobby. Our cat is a great stress reliever, so we let him go wherever he wants.'
