For the molecular genetically minded, it is a cytosine deletion in the TYR gene. Cat fanciers refer to it as the "C" locus (a sort of genetic "address"). Albino cats have been reported in scientific literature (Todd 1951; Turner et al. 1981) but their eye-colour has not always been well described. Blue-eyed albinos have not been properly distinguished from pink-eyed albino cats (Bamber & Herdman 1931; Todd 1951; Leventhal 1982; Leventhal et al. 1985). This made it
