[General] prick up one’s ears

[vil]

Dear teachers,

Would you tell me whether I am right with my interpretation of the expression in bold in the following sentence?

[FONT=&quot]Monsieur Poopoo pricked up his ears at this, and was lost in astonishment.[/FONT]
[FONT=&quot]prick up one’s ears = be all ears[/FONT] Thanks for your efforts.

Regards,

V.
