The Kentucky Humane Society officials say they’re confident they can complete a $1.6 million fundraising effort, despite a shrinking economy.The society is raising money to renovate and expand its main campus in south Louisville. Spokesperson Krista McHone says the organization raised most of the necessary funds before this fall’s financial downturn, and she expects dedicated donors to help the society reach its goal, despite the hard economic times.“Definitely it’s something that we’re concerned about," she says. "But we’re also pretty optimistic that we’re going to be able to get this done.”The society has several months to finish fundraising. Groundbreaking for the expansion is scheduled for next spring.
