The Kentucky Humane Society will again open its south Louisville food bank Saturday to offer free pet food to owners who are at risk of having to give up their pets because of financial difficulties.Spokesperson Michelle Ray says more than 150 people visited the food bank last weekend."This is something that we plan to keep doing as long we have food available," Ray said.The food bank will be open from noon to 4:00pm Saturday at the Humane Society's main campus on Steedly Avenue in south Louisville.Ray says because of the overwhelming response last week, the organization is accepting donations of dry and canned dog and cat food.
