24 clips culled from 60 hours of footage
Working with her research supervisor Paulo Steagall, Marangoni analyzed a database of 60 hours of video recordings, primarily captured during clinical studies of pain in cats conducted by the Steagall lab at the FMV. The videos document various types of pain—medical, surgical, traumatic and orofacial—in cats of different breeds, ages and sexes.
“These videos were recorded when cats were admitted to the FMV for treatment or surgery,” Marangoni explained. “We have a pain management protocol; after filming each cat for a few seconds, we administered pain relief.”
After reviewing the 60 hours of footage multiple times, Marangoni selected 24 video clips based on clarity, educational value and a “feline grimace scale“ developed at FMV.
The 24 excerpts, averaging 33 seconds in length, illustrate the 24 specific behaviours listed in an “ethogram”—an expert-validated inventory of pain-related behaviours in cats—that has been published in the journal PLOS ONE. The video clips have been posted to the YouTube account of Professor Steagall, who now teaches at the University of Hong Kong.
The videos cover a wide range of pain-related behaviours, including:
- posture and body position
- affective-emotional states
- vocalization
- feeding
- facial expressions
