The picture of Tiki's eyes (a tabby cat aged, maybe, 10 to 14) shows that her eyes are 'marbled', that is to say overall green but with an irregular pattern of brown 'marbling'.
I know that patches of brown coloration may be an indication of melanoma but Tiki's eyes are consistently 'marbled' in an even fashion.
However I have never seen eyes quite like hers before and I wonder if this is common, or not.
Otherwise, despite having been a somewhat reclusive stray for at least two years, and now that she has felt confident enough to settle down in a domestic environment, her health and appetite and functions are all excellent. So my worries about a possibly extensive melanoma are receding and I am favouring a genetic reason for her 'marbled' eyes.
Can anyone be definitive about this ?
