JACKSONVILLE, Fla. (AP) _ A zoo visitor who hurdled a four-foot wooden fence to feed a caged Bengal tiger was mauled by the 350-pound animal Tuesday and may lose an arm, authorities said.

Sandra Lee Wilson, 36, of Atlantic Beach, was listed in satisfactory condition Tuesday night at St. Luke's Hospital. Surgeons worked to save her left arm, which one paramedic said was nearly severed.

A finger on her left hand was torn off and a leg severely injured, officials said.

Ms. Wilson had jumped a fence at the Jacksonville Zoo, walked eight feet to the metal bars of a cage holding two tigers and stuck her left hand in to feed one some bread when it attacked, zoo officials said.

''We don't feel guilty about it,'' said Penny Thompson, president of the Jacksonville Zoological Society, which manages the city-owned zoo. ''We're sorry it happened here, but we are very fortunate this has never happened before.''

Signs are posted around the zoo warning visitors not to feed the animals, said acting zoo director Tim Krause.

While waiting for paramedics, Ms. Wilson ''said it her fault and that she shouldn't have done it,'' said zoo veterinarian Doug Page. ''She was very regretful and very apologetic. She expressed concern that we would do something to the cat.''
