Walmart has teamed up with the American Society for the Prevention of Cruelty to Animals (ASPCA) for a Facebook campaign aimed at saving and improving the lives of animals. The campaign encourages Facebook users to visit www.facebook.com/lendapaw to support the ASPCA. Facebook users can click on the "Create a 'Lend A Paw' post button, and Walmart's pet suppliers, will donate $1 for each post (for a total donation of up to $100,000).
