Good point. This one suffered from inbreeding, which I understand is even more of a problem now than in the 1970s. He would have panic attacks and ride around on Mom’s back, sniveling in her ear.
Once upon a time a GF had a crossed eyed Siamese that was patially deaf and spent many, many hours sitting and staring at one corner of the room, oblivious to everything going on around her...except to whatever ultrasonic signals the electic can opener transmitted.
Always wondered at the selective breeding that chose their voice as something beautiful and desirable with the dream of being surrounded by such unearthly noise.
