Caught on camera, the incident caused the bemused lecturer to shriek in surprise when a grey kitty seemingly appeared from nowhere.
And it certainly caught the attention of students learning about the Theory of Change. For what better way is there to illustrate being prepared for something happening out of the blue than a near cat-astrophe?
After sending a few ceiling tiles hurtling to the ground and landing on all fours, the cat decided to make a quick exit to the right.
But finding there was no way out, it didn't pussyfoot about and swiftly changed direction.
The hapless feline was eventually shown the door, when the teacher - still clutching his chest from the shock - asked his students to let it out.
After such a grand entrance, it seemed the scaredy-cat was more than happy to make an even quicker exit.
