I really loved this. I don't think I've ever read an end of the world book that isn't about zombies or aliens or something. The cause for all the animals sounded pretty plausible to me, and I'm slightly paranoid about my animals being in a bad mood now. The government annoyed the crap out of me in his book, but I honestly don't think they would really act any differently if this were to happen in real life. I had this on my bookshelf for over a year, and I'm glad I finally got around to picking it up.
