Cute story. But slightly misleading headline: it led me to expect that the guy did some rubber-duck debugging talking to his cat. Turned out it was "I can't figure out where the beeping is coming from, but my cat, who is smaller than me and can fit into tighter spaces, found it for me".
That's only misleading because you were expecting it to be more of an exaggeration than it was.
If it's misleading, it's because the cat debugged the computer's power supply issue, not stable diffusion per se.
