当人钱多得能养狮子，老虎和熊做宠物，未必是件好事。

(CNN) -- A 37-year-old Pennsylvania woman died Sunday after being mauled by her pet black bear, authorities said.

Kelly Ann Walz was attacked when she entered the bear's cage to feed the 350-pound animal and clean its cage, according to Pennsylvania State Police. The bear lived in a 15-by-15-foot steel and concrete enclosure on Walz's property in Ross Township.

The bear wasn't the only unusual animal living on the property, an official with the State Game Commission told CNN affiliate WFMZ-TV. The homeowner had a permit to keep a Bengal tiger and an African lion, and the property routinely passed inspection and had no violations, he said.

A neighbor shot and killed the bear that attacked the owner, state police said.
