Mitchiri Neko Lab

Mitchiri Neko Lab is a game in which you summon cats into a Jar using Seeds and see them multiply through the process of Mitosis. The objective of the game, like most Mitchiri Neko games, is to discover and collect all the kinds of Neko (Cats) there are. In order to achieve said objective you must scoop the cats to obtain Lab Points which are the currency in the game. Lab Points are used to buy food, as well as new Backgrounds and Jars in the Black Cat Store, which in turn are used to unlock more types of Neko, and the cycle repeats. In the Cat-alogue ("図鑑" zukan in japanese, meaning "Picture Book") you can see the different types of Neko you've collected. By clicking on each Cat's "Hint" Button, you can see how many Lab Points it grants when you scoop it and how many you have collected. At the bottom of each Cat Card there is a large yellow button that reads "See Generation Conditions" (hassei jouken wo miru "発生条件を見る" in japanese) where it tells you how the Cat can be unlocked. By meeting the requirements in the Generation Conditions section, new Cats can be uncovered and unlocked, collecting little by little all of the Neko in the game.

First Tab
In the First tab of the Cat-alogue, the Neko are obtained by simply matching the required Background or Jar that the Generation Conditions section. Sometimes you only need a Jar, sometimes it's a combination of Jar and Background.

Second Tab
In the Second tab of the Cat-alogue, the Neko are obtained not only by setting the required Background and Jar, but also by getting Neko from the first tab of the Cat-alogue. The Cats then combine to form the new Cat, which will appear unlocked in the Second tab of the Cat-alogue.
