Cats
black nose and paws. Amber cats are basically black cats with a colour modifier that affects
the deposition of pigment on the hair shaft, but not the skin colour. That is why in non-agouti
cats the nose remains black and in agouti cats it remains pink.
PLATINUM
The platinum effect is found in some lines of Silver Persian/Chinchilla Longhair. In 1986/7,
Cheryl Bennett reported in The Silver and Golden Persian Newsletter (ACFA) that one of her
shaded silver females (Kelley Lane Contessa of WeANDE) had changed from pure silver to
pale golden. Contessa’s parents were a shaded golden and a shaded silver; these were full
siblings. At 10 – 12 months of age, Contessa began to “tarnish” i.e. show cream/reddish
patches and by 3 years of age she was entirely pale golden. She produced a number of Silver
Persians without tarnish, but she failed to produce any offspring when mated to a golden sire.
One of Contessa’s male offspring turned from silver to golden as an adult
