I'm just curious what can cause the interlacing of eye colors in cats? To explain what I mean, below is a picture of my sister's cat Simon. I've searched all over the net and found no mention of this. Thanks.
Heterochromia - is a term used to describe variations in the color of the iris, the colored portion of the eye. 'Heterochromia' is also used to describe a multi-colored iris within the same eye, or two eyes with distinctly different colored irises. This condition can occur in cats and dogs. Vision is completely normal in these individuals and heterochromia is not considered a medical problem but rather a normal variation in eye color.
