OMIGOSH! What an amazing thing to do for a little girl! This made my day :) From Seattle Children's Hospital:

Maga is a cat-loving teen patient with cancer at Seattle Children's Hospital. She's had to be in the hospital many times, and during her stays what she misses most is her own cat Merry. We asked our Facebook fans to share their favorite cat photos with us, and got an awesome response -- 3,000+ photos! We used these pictures to create this "cat immersion" for Maga -- an audio/visual experience to bring thousands of "virtual" cats to Maga's room.

Our thoughts are with you, Maga!
