Challenge related: You are using a natural light in a artificial light challenge.
Technical: The shot is nice. The focus is a little soft and a softer light would have worked very well with this photo. that could have been achieved just by darkening the photo a little. The portion of the window right about the cat is so bright that it sort of takes away from the cat.
I'm pretty sure that there's some sunlight involved in this shot. Even if I'm wrong, the picture, I feel, is a technical failure. Poor composition, weak colors, over-exposed, etc.
The source of lighting appears to be sunlight - which is not using one source of artificial light as the challenge directed. Aside from that, the image is over-exposed for the amount of lighting coming through the window. The feet being cropped off and the odd stance of the cat make the composition weak.
