Shironeko, the famous Zen-Cat has passed away at 18 years old.

In 2006, a picture of a cat with white yellow fur and a face always in a state of “sleepy” appeared online and received the love of many people. That was Shironeko.

Since its popularity, Shironeko is considered by many people to be the happiest and sleepiest living cat in the world. Because Shironeko has eyes that never seem to open and can sleep at all times.

In addition to her eyes, Shironeko is also lovely because of her fat body as well as her white fur. Shironeko sleeps everywhere, from the garden to the house, from the table to the floor and even in the grocery bag. In general, wherever the cat is comfortable sleeping.

As of March 2, Shironeko has been sleeping the eternal sleep of her life, aged 18. However, until today (March 8), right on Shiro’s birthday, the cat’s family decided to announce the sad news.
