CBS’ summer series have afforded many a punchline in recent years, between the recent un-doming of Under the Dome, or next summer’s “Congress Ate My Brains,” and now Zoo will keep animal action alive with a second season in 2016.

In actuality, the renewal comes a little surprise, Zoo ranking among the most-watched new scripted series of the summer, and the tendency of additional seasons’ to iron out creatively. Adapted from James Patterson’s 2012 novel of the same name, CBS’ Zoo stars Mad Men alum Bob James Wolk as yes, “renegade zoologist” Jackson Oz, alongside Nora Arnezeder as Chloe Tousignant, Game of Thrones alum Nonso Anozie as Abraham, House of Cards player Kristen Connolly as Jamie, and Twilight star Billy Burke as Mitch.

So reads the official Zoo logline:

In the series, a wave of violent animal attacks against humans begin taking place across the globe. As the assaults become more cunning, coordinated and ferocious, a young renegade biologist (James Wolk) is thrust into the race to unlock the pandemic’s mystery before there’s no place left for people to hide.

Says CBS of the renewal:

Zoo’s thrilling stories clicked with audiences each week during a very competitive summer. We’re excited for viewers to see where our talented writers and cast take them as the adventure continues to unfold during season two in the ultimate fight of man vs. beast.

And there you have it. Fear your schnauzer (again), as Zoo debuts anew for Season 2 next year.
