cat shelter Purina Cat Chow is celebrating their 50th Anniversary by helping to improve cat shelters across the country. Each state has one shelter that will receive up to $1,000. You just select the state you want your donation to go to and a $1 donation will be made. You can click once a day each day until June 14, 2013. Each of the 50 shelters will also receive a delivery of much needed supplies.
