Oh they really are gorgeous! I hope my boy will be that handsome when he grows up! You can't really tell from my signature pic because in that photo the light gave Sonic a sort of brownish tint to his fur, but they are the same colour as he is, I really feel as if I might be looking at the grown up Sonic of the future when I see your two beauties!
I've been trying to find one of where they sleep - here it is. They are way too big to both be lying in here, but they do anyway! The cat tree will collapse one day.
