while it may well be a coincidence, I find vulcan’s response to the car passing by interesting. Instagram put the audio out of sync by just a few seconds but, you can see he ignores the sound of my rats drinking since he hears it all the time, but when the car passes he stops in his tracks and seems to listen intently. one of my past females, tiny, did a similar thing when she heard a car alarm on my street. cool stuff!
