A Catseye is an obtainable item unlocked when reaching User Rank 1,600. Catseyes allow units to be upgraded past Lv.30. Each Catseye allows the player to increase the maximum normal level cap of a unit by 1, but the player still needs to use XP to upgrade the Cat to that level. The maximum cap level increase allowed by using Catseye is level limit of +10, which is increased to +20 if An Ancient Curse is beaten. Legend Cats may not be upgraded above Lv.30 until An Ancient Curse is beaten, after which they can be upgraded to Lv.40. They can be upgraded to Lv.50 after clearing Revival of Origin.
Example: a unit can reach Lv.30 normally with XP upgrades. Using one Catseye will increase that unit's level cap to Lv.31+, with maximum up to Lv.40, or Lv.50 if the player has beaten An Ancient Curse. From Lv.46 to Lv.50 and Lv.56 to Lv.60, two Catseyes are needed per upgrade.
Therefore, the total Catseyes use to increase the level cap of a unit from Lv.30 to Lv.50 = 25 Catseyes. For Uber Rares from Lv.50 to Lv.60, it'll charge you 15 Dark Catseyes.
The Cat Unit also has to reach level 30 from XP upgrades first, therefore making it impossible for a player to use Catseyes on certain units before reaching specific User Rank levels, even if a player gained Catseyes beforehand.
Currently, there exists 6 types of Catseyes: Special, Rare, Super Rare, Uber Rare, Legend and Dark. The first four can only be used on Cats of their specific rarity, Legend Catseyes can be used on any rarity, including Legend Rares, and Dark Catseyes are the same, but can also be used to upgrade Uber Rares beyond Lv.50 and up to Lv.60.
From left to right respectively: Special, Rare, Super Rare, Uber Rare, Legend and Dark Catseyes.

Notes[]
Legend Catseyes and Dark Catseyes may be used as a substitute for other Catseyes if the player doesn't have enough, though it's generally ill-advised to do so.
Special Catseyes appear in the form of 4★ upgrade materials, obtainable from achievements tied to the collab stages. Rare Catseyes also appear as 4★ upgrade materials that can be obtained as special drops from sending a GAMATOTO helper out to explore. Legend Catseyes drop from every main collab stage, once again in the form of an upgrade material.
