About this Mod

Catify Mod

This is a purely client-side mod that turns your player model into a cat!

It only changes your model visually and doesn't affect any interactions or physics.

Cat Standing

Cat Variant

You can choose any cat skin. That's 11 vanila skins + any amount of custom skins.

Just run /catvariant <name> to change the cat skin!

Cat Variants

Custom Skins Supported!

To add an own skin, go to your minecraft folder, then data/catify_custom/custom_cat_skins, put a texture there and it will now automatically appear in the list!

You can find example textutes in an example folder nearby.
Custom Skin Variant

Cat Hand

You can make it so your hand in 1st person has a cat hand skin!
This is togglable with /cathand <optional on/of>

Cat Hand

Custom skins can have a custom cat hand too!

For that, place the required player skin texture in
data/catify_custom/custom_cat_hands and name it the exact same name as the custom cat skin earlier (custom cat hand requires a custom cat skin, but you can take both from the example folder nearby.

Invisibility Behavior

Because YOU CAN'T see ARMOR on the cat, it can be disorienting in 3rd person, when your player is invisible.

You have 3 options to chose from what you want it to behave like:
/catinvisibility <never/vanilla/charged>:

Cat Invisibility Modes

  • Never - your cat model will never go invisible
  • Vanilla - your cat gets invisible if the player does so
  • Charged - you see an effect similar to charged creeper's glow instead of the cat to indicate where it is technically invisible

Also, since you don't see your armor, it's recommended to use some "armor hud" mod with this for better competitive experience.

Damage Indication

You can toggle whether to show the damage on the cat with this command:

  • /catdamage <optional on/of>

Cat Mode Switch

You can always fully disable the mod's functionality with one single command:

  • /catmode <optional on/of>, so you can quickly fully disable the cat mode if needed.

Cat Mode Switch

This will toggle the cat hand too, so it's a completely global switch.

Configuring Affected Menus

You can use a keybind to whitelist or unwhitelist a menu (screen) you have opened right now to either replace the player with a cat there or not.

Toggle Menus

Usage on Servers

This mod is completely fine for using on a server.

This mod does NOTHING that can change the physics or interactions: you're still always 2 blocks tall and your eye position is normal.
Cat Player Hitbox

The cat technically doesn't exist in the world, it is only manually stored in memory and is just rendered instead of the player.

There should be no chance a server anticheat can notice a difference, so it's completely fine to use. It's purely cosmetic.

Notes

  • All settings that you change with commands are saved between sessions, including cat skin, cat hand, cat mode.

Server lagging with Catify – how to optimize performance?
