Sniffing the incessant 'aroma' that burrowed into his nose, Shi San grumbled to himself.
Big Dog must be gobbling up the feast all by himself!!!
The next moment.
Squeak, squeak, squeak~
A barrage of panicked and irritable squeaks seeped through the gap in the inadequately closed door.
Shi San shuddered and quickly covered his mouth with his paws.
What's Big Dog up to?
Those mouse squeals are frightfully canine...
...
Inside the room.
Brian looked at the struggling black-furred giant rat, whose eyes had turned a true shade of red, and somewhat disappointedly rubbed his stinging throat.
Ultrasonic waves are different from infrasound.
Ultrasonic waves are so high-frequency that they go beyond the range of human hearing, which is why they're called ultrasonic.
In fact, Shi San could hear a part of the ultrasonic sounds emitted by Brian.
Similar to cats and dogs, they can do that.
They can also hear a range of infrasound frequencies.
