When we think of cats’ eyes, we generally think of eyes of the same color. However, in both humans (like musical artist David Bowie) and animals – including the mysterious feline and dogs – there are instances where eyes come in two different colors.

In a condition called complete heterochromia, the whole iris of one eye is a different color from the iris of the other eye.
Partial heterochromia, meanwhile, is said to occur when part of one iris is a different color from the rest of the iris in one eye.
The complete form of heterochromia stands out in both beauty and intrigue. One eye will, for instance, be blue while the other will be green, yellow or copper.
