Fig 1.
Arrangement of a testing room.
There were slight differences across testing rooms depending on cats’ familiar spaces (house or cat café). The Experimenter placed speaker 1 outside the test room and speaker 2 inside the test room close to another door or window leading to another room or outside. Cats were left alone and could move freely. Cat behaviors were recorded by video cameras during tests.

The magnitude of subjects’ surprise rated by eight blind raters in Exp.1.
Black blue bar represents Diffsound. Orange bar represents Samesound. Left panel represents Difflocation and right panel represents Samelocation. Each point represents mean magnitude of surprise for each trial.
Fig 3.
Latency to look back at speaker 2 in (A) Exp.1, (B) Exp.2, and (C) Exp.3. Orange boxplot represents Samesound, black blue boxplot represents Diffsound.
Fig 4.
The magnitude of subjects’ surprise rated by eight blind raters in Exp.2.
Black blue bar represents Diffsound. Orange bar represents Samesound. Left panel represents Difflocation and right panel represents Samelocation. Each point represents mean magnitude of surprise for each trial.
Fig 5.
The magnitude of subjects’ surprise rated by eight blind raters in Exp.3.
Black blue bar represents Diffsound. Orange bar represents Samesound. Left panel represents Difflocation and right panel represents Samelocation. Each point represents mean magnitude of surprise for each trial.
