A cat-loving teen being treated at Seattle Children's Hospital got a big surprise yesterday.

The folks at Seattle Children's say Maga has had to be in the hospital many times, and what she misses most is her cat, Merry.

A couple of weeks ago, they asked people to send in their favorite kitty photos for Maga. The response was immediate - and more than 3,000 photos were submitted via Facebook.

The photos were used to create a "cat immersion" for Maga - an audio/visual experience to bring thousands of "virtual" cats to Maga's room.

Maga was surrounded by cute cats of all shapes, sizes and colors.
