Is this a "Black" cat?

Dear all,

Finally, I managed to captured a pretty realistic photo of my Black cat. Is it really a Black cat? I really start to wonder. When I first take him home, he is BLACK cat. Now ....

終於有機會映到張似樣的黑貓相. 牠真的是黑色的嗎? 我買牠的時候是黑的... 是否開始老了 .....

Forgot to attach the photo again.

My friend have a little  black dog, but it got a same problem after 6 year when they bought it.  Grey dog now  :

The interesting thing is, this cat is "selectively" grey and black. His limbs, his head are all black as in the past but his body is grey.

奇怪的地方是, 這隻貓是局部地區黑, 局部地區灰.
