My flash tiger is still yellow and I have had this guy for at least half a year. No turning white/black at any point. Show me your jures and try to call it flash like mine.
Interesting thread this, having kept both tigs and jurence in past I fancied flash after seeing that same vid on start on this a while ago. Off to Peru in aug hopefully so will be catching cats like these so maybe have to bring some back to UK but highly doubt now that their keep their yellow colour.
