I found this and I just thought it was really intresting..
Sai Mai, a 26-month-old female tiger, plays with baby pigs at a zoo in Chonburi province, 80 km (50 miles) east of Bangkok, Thailand on May 7, 2003. The Royal Bengali tigress was born in captivity and breast-fed bya female pig for four months after her birth.
I guess that answers the age old question.. Nature VS Nurture.
