Ladies what do you think of males who cat call you in public

I get that guys have been doing this forever....construction workers, cab drivers ect ect
But seriously what should our reaction be to guys lusting with their eyes and cat calling women like your at some sports event
Should we be flattered as they think we should be
Should we ignore them? Call them out openly and tell them to stop it?
I dont know about other women but i find that type behavior in males very disrespectful, cheapenizing and degrading. Is it me or when this happens it feels like im walking near a dog pound full of barking dogs!
Males why do you do this? Is basic good manners and respect to much to ask? Ladies how do you feel about this
Any experiences with this animalistic behavior?
