Officials at Reno's Sierra Safari Zoo are issuing a plea for donations to help feed lions, tigers and other animals over the winter.
Zoo officials said it costs about $12,000 a month to feed and care for the 200 animals, and gate receipts are used to feed them when the zoo is open between April and November.
"When we're closed, we count on the generosity of the community," said zoo spokesman Dale McDaniel.
The all-volunteer operation has been hit hard by rising food costs this year, he said.
The zoo is home to about 40 species of animals, including leopards, cougars, sloths, zebras, wallabies and an alligator.
The nonprofit zoo has been in operation for 18 years and is the state's largest.
