The socialite - who already has a menagerie of animals including dogs, a hamster and a miniature pig - took pity on the furry creatures after learning they were being sold at a pet shop as snake food.
She tweeted: "Feeding My Bunnies a Late Night Snack :)
"The bunnies were meant to be feeders. I saw them at the petstore & they told me they were for snake food and I had to save them.
"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. (sic)"
Meanwhile, Paris` friends have revealed she has finally grown up since her arrest for cocaine possession and has turned her back on partying.
The 29-year-old hotel heiress - who was charged with possession of the drug after it was found in her handbag when she and boyfriend Cy Waits were searched by police in Las Vegas last month - has apparently turned her back on partying and wants to live a quieter life.
A source told E! News: "She`s actually enjoying laying low. As bad as this whole experience has been, she feels like everything happens for a reason and that it really made her slow down and appreciate life.
"She finally feels like an adult and doesn`t miss the clubs or party scene. She`s turned down lots of offers to host parties."
