Cat Companions+

Cat Companions+ gives Minecraft cats a much larger role after taming them.

Instead of existing primarily as decorative pets, tamed cats can become true combat companions that can be equipped, commanded, protected, and managed individually.

The goal is to expand cats in a way that still feels natural within Minecraft. Cats retain their familiar tameable behavior, ownership, sitting and wandering mechanics while gaining equipment, combat, behavior, and companion-management features.

Features

Cat Companion Management

Owned cats have a dedicated companion menu for managing their equipment, behavior, and settings.

Shift + Right-Click a tamed cat, or use Control + C to open its companion menu. 

The menu shows:

• Cat name
• Cat appearance
• Current and maximum health
• Damage
• Damage reduction
• Equipped armor
• Equipped weapon
• Current behavior
• Owner distance
• Guard status
• Retreat settings
• Nearby companion cats

You can also select other nearby owned cats directly from the same menu without having to close it.

Cat Behavior Modes

Cats can now be given different behavior modes depending on how you want them to act.

Follow
The cat follows you normally and helps defend you when necessary.

Stay
The cat remains around its assigned location instead of following you everywhere.

Guard
The cat protects an assigned area and actively looks for hostile threats within that area, even when you haven't attacked anything yourself.

Defensive
The cat will defend itself and its owner when threatened.

Passive
The cat will not engage in combat.

Behavior settings are saved individually for each cat.

Guard Area

Guard mode allows a cat to protect a specific area.

A guarding cat will:

• Patrol around its assigned area
• Look for nearby hostile creatures
• Attack threats without requiring the player to attack first
• Pursue threats within its allowed range
• Return to its guard area afterward

Guard areas make cats useful for protecting bases, farms, villages, entrances, and other locations.

Companion Combat

Cats can actively participate in combat alongside their owner.

Cats are capable of:

• Surrounding enemies instead of stacking in one location
• Moving around targets while fighting
• Choosing safer attack positions
• Repositioning after attacks
• Performing short pounces when appropriate
• Avoiding dangerous attack paths
• Working together when multiple companion cats are present

Cats remain support companions rather than replacing the player's own combat ability.

Low-Health Retreat

Cats can be configured to retreat when their health becomes low.

Retreat can be turned On or Off, with three available health thresholds:

• 10%
• 30%
• 50%

When retreating, the cat stops pursuing enemies and attempts to move toward a safer location.

The cat can retreat toward:

• Its owner when following
• Its assigned location when staying
• Its guard area when guarding

Cats also avoid immediately returning to combat until they have recovered enough health.

Hazard Avoidance

Companion cats are much more careful around dangerous terrain.

They attempt to avoid hazards such as:

• Lava
• Fire
• Soul fire
• Campfires
• Cactus
• Magma
• Powder snow
• Dangerous falls
• Other recognized dangerous paths

This helps prevent companion cats from needlessly killing themselves while following or fighting.

Recall

Recall calls a companion back to its owner.

When recalled, the cat:

• Returns safely to the player
• Switches to Follow
• Stops sitting
• Resumes normal companion behavior

Recall also checks the destination so the cat isn't intentionally placed inside dangerous terrain or another unsafe location.

Sit & Stand

Cats can still be manually told to sit or stand.

Sit temporarily stops the cat from moving, fighting, patrolling, or pursuing enemies.

Stand allows the cat to resume its previously selected behavior.

Sitting does not erase the cat's saved behavior settings.

Multiple Companion Cats

The companion menu can display multiple cats owned by the player.

Each cat can be selected individually to view its:

• Appearance
• Health
• Equipment
• Distance
• Behavior
• Current status

Cats also use improved positioning during combat so several companions are less likely to occupy exactly the same space around an enemy.

Cat Companion Inventory

Owned cats have their own equipment interface for managing companion gear.

The inventory provides dedicated places for:

• Cat armor
• Weapons

The menu also displays important information about the selected cat, including its name, health, damage reduction, damage, equipment, and current behavior.

The companion inventory is separate from normal vanilla cat interaction so normal sit/stand behavior remains available.

Custom Cat Armor

Cats can wear specially modeled armor designed specifically around the Minecraft cat body.

Current armor tiers include:

• Iron Cat Armor
• Gold Cat Armor
• Diamond Cat Armor
• Netherite Cat Armor

Armor is visibly rendered on the cat rather than simply existing as an invisible stat bonus.

Each material uses the same fitted armor design with its own appropriate material appearance.

Visible Weapons

Cat Companions can carry weapons visibly in their mouths.

Rather than simply increasing damage invisibly, the equipped weapon becomes part of the companion's appearance and combat progression.

Persistent Equipment & Settings

Each cat keeps its own equipment and companion settings.

This includes:

• Armor
• Weapon
• Behavior mode
• Guard location
• Stay location
• Retreat settings

These settings remain associated with the individual cat through normal world saves and reloads.

Vanilla-Friendly Design

Cat Companions+ builds on Minecraft's existing cat system rather than replacing it with an entirely different pet system.

Cats retain familiar mechanics such as:

• Taming
• Ownership
• Sitting and standing
• Normal movement
• Cat variants
• Existing vanilla cat behavior where appropriate

The additional companion features are layered on top of the familiar Minecraft cat.

Minecraft-Style Design

The armor, equipment, combat system, and interface are designed to remain visually compatible with Minecraft rather than turning cats into heavily over-designed RPG characters.

The focus is on:

• Recognizable vanilla cats
• Useful companion behavior
• Lightweight equipment progression
• Visible gear
• Simple controls
• Individual companion management

Cat Companions+ is required on both the client and server.

The server controls companion equipment, behavior, combat, health, damage reduction, weapon damage, and persistence.

The client provides the companion menu, equipment display, armor rendering, weapon rendering, and other visual features.

Description

Cat Companions+ gives Minecraft cats a much larger role after taming them.

Instead of existing primarily as decorative pets, tamed cats can be outfitted for adventure with custom cat armor and weapons, allowing them to accompany and help defend their owner during exploration and combat.

The goal is to expand cats in a way that still feels natural within Minecraft. Cats retain their familiar tameable behavior, ownership, sitting and wandering mechanics, while gaining a lightweight equipment and combat system built specifically for them. Features Cat Companion Inventory

Owned cats have their own equipment interface for managing companion gear.

Cat Inventory GUI is accessed by holding Shift and Right-Clicking your cat.

The inventory provides dedicated places for equipment such as:

Cat armor
Weapons

This menu also details your cats name (if given a tametag), Current/Max Health, Damage Reduction Percentage, and Damage

The companion inventory is separate from normal vanilla cat interaction so normal sit/stand behavior remains available. Custom Cat Armor

Cats can wear specially modeled armor designed specifically around the Minecraft cat body.

Current armor tiers include:

Iron Cat Armor
Gold Cat Armor
Diamond Cat Armor
Netherite Cat Armor

Armor is visibly rendered on the cat rather than simply existing as an invisible stat bonus.

The armor follows the cat's body while it:

stands
walks
runs
sits
turns its head
fights

Each material uses the same fitted armor design with its own appropriate material appearance.

Crafting costs: Armor Cost Iron 6 iron ingots + 1 leather Gold 6 gold ingots + 1 leather Diamond 6 diamonds + 1 iron cat armor Netherite Smithing: diamond cat armor + netherite upgrade template + netherite ingot Visible Weapons

Cat Companions can carry weapons visibly in their mouth.

Rather than simply increasing damage invisibly, the equipped weapon becomes part of the companion's appearance and combat progression.

Weapon tier determines the cat's attack strength.

Current intended damage progression is: Equipment Damage No weapon 2 Wooden 3 Stone 4 Copper 4 Iron 5 Gold 6 Diamond 7 Netherite 8

This keeps an unarmed companion relatively weak while allowing a properly equipped cat to become increasingly useful during progression. Combat Companions

Equipped cats can help their owner in combat.

The system is designed around cats being support companions, rather than replacing the player's own combat ability.

Better equipment provides:

increased survivability
improved attack damage
visible progression
another reason to bring a favorite cat while adventuring
