From Temple Run to Flappy Bird, it is easy to be consumed by the popularity and addictiveness of apps. The latest app gone viral is a game from Japan, and unlike other intense and sometimes infuriating games, it has a simple objective: collect as many cats as you can.

The game “Neko Atsume,” which translates to “Kitty Collector,” is a simple yet addictive app in which players attract cats to their virtual yard. It’s available for free for both Apple and Android products.

If you decide to give into the cat craze, it may take a while to get into the game. After you first place food in your yard it takes over 30 minutes for cats to begin arriving. It does not have the same instant gratification that other games have and is instead one that picks up over time. However, once the cats begin coming it is easy to understand the love for the game. When the cats come, they leave fish as gifts. Players can then use these fish to buy goodies and toys to put in their yard. The more toys in your yard, the more cats you lure in.

Soon, you’ll be constantly opening your app to find cats playing with balls of yarn, getting stuck in buckets and tubes and entertaining themselves with the wide variety of objects found in your yard. There are many different cats with different personalities and names that you can choose yourself. Players can also take pictures of the cats and save them to albums in the app, so even when your yard is empty you can still see your favorite cats.

Some may wonder: what’s the big deal? They’re just virtual cats playing in a virtual yard. However, for cat lovers this is an exciting game that allows you to carry the cute furry animals around with you at all times. This clever and simple app, free in the app store,  is reminiscent of Webkinz, Club Penguin and other virtual animal games from your childhood, and it provides adorable entertainment.
