I hope you'll be able to help me out on this, but if not its perfectly fine! I was petting my cat (hes an American short hair) and I noticed he has a star design in his eyes. He has brown/orange eyes, but he has 2 little blue "spikes" on each side of his pupils, as well as on the top and bottom of his pupils. It makes his eyes look like the north star. Is it just a version of heterochromia or is it something else? I haven't found anything like it, so I don't know what it is. Have a nice day!
