Um, I had to remember what "cat calling" actually means. I used to think it was funny when I was younger and whistled at, didn't take offence. These days (obviously) it hasn't happened much in recent years. However, not that long ago one of the local single men, probably a bit younger than me "wolf whistled" me as I walked past him on the other side of the road, and I didn't really like that, mainly because he had once before made a comment about the lovely sunshine and when am I going to see you in your bikini in the garden. So maybe it's about context.
I don't think it's worth making a huge fuss about.
