Yeah, I was expecting a much different thread as well! I had to click out of curiousity because that
other type of catcalling isn't something I've seen or heard of in Brandon!
Anyways, as for the original post, my understanding is that cats don't normally vocalize with meows unless they're raised with humans. The meowing that we're used to is literally an attempt to communicate with us, to mimic the noises we make to them, so it could easily be that your cat is trying to say hello to you!
