Plants make ultrasonic sounds that can be heard under stress

I wonder if cats can hear it?

I bring my pepper plants in for the winter and put them in a room where I keep the door closed otherwise my cat will destroy them. I always know when they need to be watered because my cat will sit in front of the door meowing nonstop and sure enough they will be drooping needing water. After that cat shuts up and doesn’t care until it’s time to water them again later.

It’s like clockwork

If trees could scream, would we be so cavalier about cutting them down? We might, if they screamed all the time, for no good reason.
