“It’s like part purr, part meow? Pureow?”
That could be it, it sounds like it comes from their throat, like the purr does.
For someone who claims not to know much about animals, I think you know cats pretty well!
Lol I always had cats. Yes, it comes from the throat - they don’t even have to open their mouths. It’s like they want to meow about something, but change their minds and make it a purr - less energy.
I do like cats. I like dogs as well. I just don’t want one. I think you have to LOVE them to give them good homes.
Up here, they call that “trilling.”
It’s a sweet sound!
I love the sound when they trill!
