I've noticed a strange thing with my cats. When I drive with them in my ICE, they are constantly yowling. But when I carry them in my EV, there's not a peep. Has anyone else experienced this?
I suspect there are ranges of sounds coming from ICE vehicles humans can't hear that cats (and dogs) can hear, so it would not surprise me. My dogs are a lot more relaxed in my EV – no noises, vibrations, or odors like in an ICE car.
Engines have a sound not far off from a low growl that an aggressive critter emits before a fight. EVs sound much friendlier. Bob Wilson
