I do agree with you of course. However, I have a gut feeling that 
something else is at play here. Possibly involving the slight 
reflectivity mentioned by Norbert, or something involving a high 
"ambient" value (?). Look also at the left-hand chair: It should be in 
shadow (light coming from left rear) but it is strongly illuminated by a 
light from under the table... Is that reflection from the table cloth? 
It seems too bright to me.

But those are just nitpicking comments. The image is gorgeous nonetheless.

A peaceful and complex scene, with many interesting elements. The fur of 
the cats could be not perfect, but works, and also the poses are very 
nice, they seems really interested to the light and to the context.
I like it!

You know there are days when I despair of ever getting to this level.
Really great image - love it
