Iris Grace Halmshaw is a 4-year-old girl from the U.K. Facebook: Iris-Grace-Painting In December 2011, Iris was diagnosed with autism. She struggled with communication, expressing affection, and social interaction. After her diagnosis, Iris' parents looked for activities through which she could effectively express herself. Facebook: Iris-Grace-Painting They also introduced a new friend into Iris' life. In February 2014, they brought Thula the Maine Coone home, and it was the "beginning of a beautiful new friendship." With Thula around, Iris became more verbal and open. Facebook: Iris-Grace-Painting Before Thula, Iris was extremely uncomfortable wearing clothes. With her new friend around, she began "wearing her clothes, sleeping better and communicating more." Thula is more than just a therapy cat, she's Iris' faithful best friend. Facebook: Iris-Grace-Painting The pair are inseparable, as Thula stays by Iris' side as much as possible. Facebook: Iris-Grace-Painting One of Iris' favorite activities is painting, and Thula is Iris' assistant, sitting quietly while watching her work. She chats with Thula about all sorts of things, even teaching her about sea creatures when Thula joins her for a bath. Facebook: Iris-Grace-Painting Thula listens intently as Iris goes through the sea creatures one by one, waiting to get out of the bathtub until Iris is ready. Despite her patience and good nature, Thula can be a bit mischievous like any other cat. Facebook: Iris-Grace-Painting She was caught playing with one of Iris' favorite paintbrushes one afternoon. "Anyone else would've been scolded for it, but Iris made an exception for her best friend." Thula even received a gold star from Iris' special sticker collection. Facebook: Iris-Grace-Painting Before Thula, Iris' mother attempted to use the "gold star routine" to reward good behavior. Iris was horrified, though, when a gold star sticker would be removed from the paper. The stickers were stowed away in a safe place until one afternoon when Iris went in and pulled one off the paper, placing it on Thula's forehead. The pair does nearly everything together, and Thula is innately in tune to Iris' emotions and needs. Facebook: Iris-Grace-Painting They share a daily after-lunch nap...
