We have released the following update.

Support for International Cat Day on August 8
Added 9 new achievements, including ones related to International Cat Day

We have also fixed minor bugs and malfunctions.

To all cat lovers, thank you as always for playing Sill Cats.

To celebrate World Cat Day on August 8, Sill Cats will present the following modest gifts to everyone who launches Sill Cats on that day.

• A special achievement

A special achievement will be unlocked as proof that you launched Sill Cats on August 8.
This achievement is not limited to 2026; you can also unlock it next year and beyond by launching the app on August 8.
Note: Once you have unlocked the achievement, there is no need to unlock it again in later years.

• A special cat toy

We are giving everyone the maneki-neko, long known in Japan as a lucky charm that invites good fortune and prosperous business.
This is the 2026 version, and we hope to give you a different one next year and beyond.

We will keep updating Sill Cats little by little, so we hope you will continue to enjoy it.
