Customization is a gameplay element in Cattails. It allows the player to customize their cat's appearance. There are three customization types available: accessories, coat colors, and eye colors.
There are currently 98 accessible coat colors and 13 eye colors.
The player can customize their cat by opening their inventory and selecting Change on the right side, or by opening the inventory and pressing the space bar. In the customization menu, the player cat's eye color and accessories can be changed in the left panel (next to the cat eyes icon), while coat color can be changed in the center panel by selecting any of the square-shaped icons.
The player can change their eye color anytime. There are thirteen default eye colors available. The player cannot unlock or buy new eye colors. The player cat's kittens can inherit their eye color, their mate's, or a mix of both parents' colors.
Most accessories and coat colors can be bought at shops. However, there are other ways to obtain coat colors:
Fulfill requirements (See: Special Conditions below for more info.)
Early Access or Kickstarter backer
Coat colors can be used to customize the player cat's fur. There are 6 default coat colors available. Other colors can be bought at shops, earned through special challenges, or unlocked by entering promo codes.
Promo codes never expire. The player can copy and paste the codes in-game using (Ctrl + V). Custom coat colors that were not created by the developers were made by Kickstarter backers who backed the Radiant Rex tier or higher. These backers are not obligated to release their codes, and may choose to share it or keep it to themselves.
The “Hacker” coat color's code is a reference to Cats: Untold Tales, one of Falcon Development's first games. In the game, if the player tried to name their cat “Falconstar”, it would change to “Nicetryhacker”.
Kittens and re-colored Custom Colony cats do not receive effects given by certain coats (the translucency from Guardian and Ghost, and the color changing from Rainbow and Aurora).
