Spoke to Animals and I Make Billions

Broke zookeeper Carter was pushed into a lion pit by his vicious ex-wife so she could kill him and cash in on his insurance. But he crawled out alive, and gained a power no one has ever had: he can understand animals. Now the lion is his friend, the kangaroo is his fighter, and the birds are his eyes.... Together, they fight back against their enemy, save a dying zoo from closing for good, drag the wicked into court, and send Carter from the bottom of the world to the very top.
