Why Some Animals Eat It

Eating poop is gross! So why do some animals do it? For lots of good reasons!Male butterflies slurp up poop to give as a gift to females, which makes their eggs stronger. Robins scarf down the poop of young chicks because it’s full of undigested nutrients. And baby elephants gobble up the poop from adults to get essential bacteria into their digestive systems. This disgustingly informative book is bursting with lots of surprising information about animals-and digestion!
