Meet Pam Pam, a beautiful little kitten that has one green eye and one blue eye. She has 84,600 followers on Instagram (and counting). The condition that’s responsible for her eyes is called heterochromia iridium. It is the result of the excess of lack of the pigment melanin. It can be inherited or caused by disease and genetic mosaicism. Luckily, Pam Pam is in no pain because this phenomenon is not dangerous. Pam Pam’s Instagram page was first launched August 8th, 2016. The photos usually are close up pictures of Pam Pam’s face, but as she’s gotten more famous fans have started submitting paintings of Pam Pam that have made her Instagram. Pam Pam has even modeled different holiday clothes like a festive red flower for Valentine’s Day or a Christmas sweater.
