How about this?
(use '[clojure.contrib.str-utils2 :only [split]])
(defn cook [animals]
(map (fn [{:keys [animal sound number-of-feet]}]
(map #(hash-map :animal %1 :sound %2 :number-of-feet %3)
(split animal #"\s")
(split sound #"\s")
(split number-of-feet #"\s")))
animals))
which gives:
(({:number-of-feet "4", :sound "woof", :animal "dog"}
{:number-of-feet "4", :sound "meow", :animal "cat"}
{:number-of-feet "2", :sound "chirp", :animal "bird"})
({:number-of-feet "4", :sound "neeeee", :animal "horse"})
({:number-of-feet "4", :sound "howl", :animal "wolf"}
{:number-of-feet "4", :sound "oink", :animal "pig"}))
