More pets for Paris.

The 29-year-old heiress has Twittered that she recently walked into a pet shop and was shocked to learn that several rabbits would become food for snakes.

"I had to save them," she wrote. "I rescued 20 of them. They are now happy living in my backyard. They are all so happy, so nice to have changed their fate."

Hilton's playtime with her pets may soon be strained.

The heiress was recently charged with felony cocaine possession following her Aug. 28 arrest in Las Vegas. If convicted, she faces four years in prison.
