This could be a breakthrough in animal therapy for people who suffer from dementia.

Washington resident Virginia Smith needs 24-hour care at this point, and her son James says that she's had cats for as long as he can remember.

When she moved into an adult home in Seattle, her son realized that being "catless" was taking an emotional toll on her. He Googled "robotic cat" and was surprised to find out that Hasbro makes them for $100. So, he and his wife got her one. And it obviously has done the trick.

Good on you, James. The smile on her face is worth it, and thanks for sharing it with the world.
