The Grey's Anatomy cast has donated autographed merchandise to benefit Much Love Animal Rescue, a nonprofit organization dedicated to saving animals from abuse and neglect. The Los Angeles-based animal shelter maintains a large network of celebrity supporters, and is constantly raising money on behalf of animals with nowhere to go.

The cast has signed t-shirts that are up on eBay, with all proceeds going to the rehabilitation of stray animals. In addition to the signed shirts, the Grey's wardrobe stylist created a pair of custom shirts that were featured on Ellen when Ellen Pompeo visited earlier this month.

Check out the eBay auction here, or visit Much Love's site and make a donation today! It's a good cause. Sandra, Katherine and Ellen will be proud.
