I've read it. I'm actually reading it again with the new gurlie
There are actually very few books by Kurt Jr. that I haven't read. He is BY FAR my favorite author. I often tell people that if they want insight into me, to read Vonnegut. He writes like I think...all sporadically and such.
And man, if you liked Slaughter House Five, then read Cat's Cradle. It's another of his early ones. Breakfast of Champions is also great.
