 : I don't have access to those books anymore (and I don't want to go to a library), but I can  find the source by google for those who are interested enough. 
 :1) The Russian translation of the book  ""Compendium of history"" is 
 Рашид ад-Дин. Сборник летописей / Пер. с персидского О. И. Смирновой,редакция проф. А. А. Семенова. — М., Л.: Издательство Академии Наук СССР, 1952 
 :here is the link http://ru.wikipedia.org/wiki/%D0%94%D0%B6%D0%B0%D0%BC%D0%B8_%D0%B0%D1%82-%D1%82%D0%B0%D0%B2%D0%B0%D1%80%D0%B8%D1%85 
 :I am 100% sure it mentioned clearly that the name Borjigin means ""Blue eyes"" in that version in its records about the ancestors of Genghis Khan (I think in its vol.1) and that gives me strongest impression that Genghis Khan's ancestor might have eyes. If any English translation gives other meaning, one would have to check the original Person text to make sure. 

 :2) I was wrong, due to lack of the book at hand, but not conflating about Bodonchar, the 5th son of her mother, not the 4th. I also misremembered some other things, but that did not mislead my idea.  The exact words of the Bodonchar's mother (probably called something like Alan-Hoa, red-beauty in my memory) said a ""a gold man"" visit her tent and mate her without mentioning his hair. However, it is same when we call someone a blond girl without mention the blond color is her hair not her skin or eyes. In another language, blond girl could be called yellow girl or golden girl because the are just similar color. I also read the slaves of Genghis call themselves ""black head"" in the ""secret history"" (I don't remember where bcus no book at hand), and got a strong impression that it might be translated as black hair, namely, could be a suggestion that the slaves are Asians with black hair in contrast the the ""golden family"" that might have different color. 
 :Dog was used repeatedly in ""SHoM"" as a imageries of ""brutal warriors"". When the priests from Europe talked to the Mongols, the ""Eternal Heaven"" was translated as god. When Bodonchar's mother talked about son of heaven, it was quite possible either she or the ""later mongol historian"" made a story that this warrior with yellow hair is a son of god. This is of course a speculation, and other possibilities exist. However, there are quite a number of other similar things that support this idea and it would be quite a increditable accident that all these material exist together while the speculation does not fit the fact. 
 :I remember in a seminar, A Mongol Scholar said the word ""golden family""  exclusively means direct descendants of  Bodonchar, that includes the uncles or cousins Genghis that he killed.  That also remind me it might be a character Bodonchar's hair. My memory is not a RS of course, but I believe one soon or later could find the source, if interested enough. 
 :Now ""Blue eyes"" and ""The stupid"" In the society of Mongols, as well as all the other nomad tribes, the so-called family names were just from the name of the chief or previous chief. When a chief was dead, if his sons divide his slaves, they became several clans and the tribes names changed into the one of the new chief. But if the sons still were kept in the same tribe, like brothers of Genghis, they kept the old family name. The slaves share the same ""family name"" that was actually the tribe name. As a typical example,Genghis has two ""family names"", 1) Borjigin  from ""the stupid"" 2) something like Kijan(), the second one is his father's name.  
 :According to the ""SHoM"",the stupid"" was very despised and bullied by his brothers. IMO, this name reflected the despising, however, he became a powerful noble after he captured plenty of slaves and other properties and he owns his won tribe. It is hard to imagine he would like to keep his obedience and in the same time he remind his followers he was the bullied stupid guy by keeping his despised name as his clan name. I would say, a name of ""blue eyes"" and ""golden families"" would work much better if he had the color in his eye and hair, over the other ""black head"" Asians in his society. 
 :3)In one English translation on internet, the correct English name of the Chinese book is: Zhao Gong, “A Complete Record of the Mong Tatars”. This book  
 :4) I do not see the picture of Genghis supports he was a white too, but that picture also does not support he had ""eyes of cat"" 
 :5) There are many cats that have blue eyes. especially kittens. Persian breed of cats are known for their much higher distributions of blue eyes comparing to ordinary cats, http://designerpersiankittens.net/images/Persian_Kitens_for_Sale_5lg.jpg. Juvaini was a Persian. 
 :Also, there are quite many other ordinary cats of mixed breeds have blue eyes although much less popular than Persians cat. My own cat had blue eyes when she was kitty but green eyes after grown up. In fact I have never seen
