Catgirl & Catboy Mod 0.1.0: cat ears over armor and a meow key
The first version: 14 cosmetics in eight slots over armor, three sets, a meow key, five mobs and ten foods. Builds for Minecraft 26.3, 1.21.1 and 1.20.1.

Catgirl & Catboy Mod 0.1.0 is the first release. It adds cat ears, a tail, paws and collars that are worn over armor. There is no potion and no transformation: craft the ears from wool, string and leather and put them on.
What you wear
There are 14 cosmetics and eight slots for them to the right of the inventory: ears, head, face, neck, paws, legs, feet and tail. Armor stays in its own slots, and other players on the server see the outfit. The three ways to put a piece on are on the cosmetic slots page.
The six fur pieces come in eight coats. Six are crafted, and the color of the wool picks the coat. Siamese and Calico can't be crafted and come from mobs. Collars, bows, headphones, whiskers and blush take any dye, like leather armor.
The ears twitch and press back when you take damage, the tail sways, and a bell on the collar rings when you jump.
Three sets
- Full Neko (ears, tail, collar, paws): quieter steps, a jump about a third of a block higher and Night Vision for 10 seconds on N.
- House Cat (ears, collar): cats and ocelots follow you, and a tamed cat within 16 blocks keeps phantoms away.
- Alley Cat (tail, leg warmers, slippers): no fall damage from up to 10 blocks.
The exact numbers are on the sets page.
The meow key
Press Z and your character meows. Up to six cats within 12 blocks answer one by one. That is all the key does.
Blocks, catnip and food
- Cardboard Box: sit inside and mobs lose you.
- Cat Bed: lie down at any time of day. Ten seconds give Well Rested, +15% speed for a minute.
- Catnip grows wild in plains, meadows, forests and cherry groves. Eating it gives Haste, and cats nearby get the zoomies.
- Yarn Ball: throw it and cats chase it.
- Ten foods, among them Tuna Onigiri, Takoyaki and a Saucer of Milk that removes only the harmful effects.
Five mobs
- A Stray Neko lives in villages, sells ears, tails and collars for emeralds and can be tamed with raw fish.
- A Kitten is brought by a tamed Stray Neko and grows up into one.
- A Fisher Neko sits by rivers and on beaches and gives a fur piece in Siamese or Calico for every 10 raw fish.
- A Bakeneko comes out in dark forests and takes what you hold. In Full Neko it leaves you alone.
- A Cat Spirit takes a small flower and gives Nine Lives: your next death within one in-game day is cancelled.
Installing
There are builds for Minecraft 26.3 (Fabric, NeoForge), 1.21.1 (Fabric, NeoForge) and 1.20.1 (Fabric, Forge). The mod needs Architectury API and GeckoLib, plus Fabric API on Fabric, and goes on both the client and the server. JEI and Jade are supported, and so is Curios on NeoForge and Forge. Minimum versions are listed on the installation page.
0.1.0 has neither a config nor commands, and its sounds are vanilla: the meow is an ordinary cat's.
