Pitt has made a small zoo with geese, ducks, goats, llamas, bantam chickens, emus and lop-eared rabbits in it for his children -- Maddox, 11; Pax, 9; Zahara, 7; Shiloh, 6; and four-year-old twins Knox and Vivienne -- who he raises with fiancee Angelina Jolie, reports thesun.co.uk.

"Maddox and Pax are safari mad and they wanted Brad to buy them lions and tigers, even crocodiles. Brad decided to go with a mini farm/petting zoo theme that the twins, Knox and Vivienne, can enjoy looking after as well," a source said.

"They're in a penned-off area in a field with little huts that the animals live in. Brad thinks it is good for them to learn to look after other living creatures," the source added.
