Tamed wolves, cats, horses, parrots, and pets from other mods are registered automatically. The complete NBT data of each pet is stored separately and managed through an index.

Servers that need to reduce scanning overhead can enable performanceMode in the configuration. This disables automatic tracking and other expensive scans. Pets must then be registered manually by right-clicking them with a feather or by using /tbf load. The registration item and whether it is consumed are configurable.

The pet screen can be opened with a configurable keybind. When a compatible version of L2 Library is installed, it is also available through the Pet Companions inventory tab.

The screen displays each pet's name, health, dimension, and coordinates. Its latest status is synchronized from the server in real time.

• Click the store button to save a pet and safely remove it from the world. Click it again to release the pet.
• Storing pets has configurable distance and cooldown limits.
• Hold Shift while clicking the store button to recall multiple nearby pets at once.
• Use the mouse wheel to adjust the area recall radius from 1 to 16 blocks. The default is 8 blocks.

Pets can be summoned to their owner from any dimension. Sitting pets automatically stand up after being summoned.

If the pet's chunk is not loaded, the mod creates a pending summon and completes the teleport after the chunk becomes available. Forced chunk loading and entity deduplication prevent duplicate pets from being created.

While riding a registered pet, the Summon button for another pet that has previously been ridden changes to Swap Mount. Using it summons the new mount and automatically stores the previous one.

Hold Shift to change the Swap Mount button back to a normal Summon button.

• Standard healing consumes 3 food points and heals the selected pet for 15 seconds.
• Hold Shift to use advanced healing, which consumes 9 food points and heals more frequently.
• The remaining healing duration can be extended up to 60 seconds.
• Creative mode players do not consume food points.

When a tracked pet dies, the mod stores its state and prevents item drops, avoiding item duplication through repeated revivals. The pet can then be revived from the management screen by consuming the configured revival item. By default, revival costs one Totem of Undying.

Revived pets receive the same Regeneration, Absorption, and Fire Resistance effects granted by a Totem of Undying.

Entity types that must keep their normal death and drop behavior can be added to noReviveWhitelist or clearOnDeathWhitelist.

Removing a living pet from tracking requires two confirmation steps to prevent accidental deletion:

1. Left-click the delete button to enter the pending deletion state.
2. Hold Shift and left-click again to confirm.

When a stored pet is removed from tracking, it is first released back into the world. Removing a dead pet allows it to continue through its normal death process.

If deleteStoredPetsDirectly is enabled, the stored data of recalled or dead pets is permanently deleted without releasing the entity.

• Filter the list by pet species.
• Search for pets by name.
• Hold Shift and left-click a pet icon to assign a priority from 1 to 6 for list sorting.
• Pets carried on a player's shoulders, such as parrots, remain tracked and are automatically linked to their new UUID after leaving the shoulder.

The mod includes a dedicated team editor:

• Create up to 8 pet teams.
• Each team holds 6 pets by default. This can be adjusted up to 8 with maxPendingSummons.
• Drag pets into team slots, or select a pet and click the plus button in an empty slot.

Hold the configurable team wheel key to open a radial menu for the current team. Point at a pet and release the key, or left-click, to summon it. The wheel also supports mount swapping. Click the bottle icon to summon the entire team.

The mod separately backs up the inventory NBT of container-carrying entities, such as horses equipped with chests. Modded entities with arbitrary slot counts are supported.

On Minecraft 1.21.1, installing Curios 9.5.1+ also allows pet accessories to be backed up and restored as part of the complete entity snapshot.

The mod includes English and Chinese display names for more than 20 common dimensions. These include the three vanilla dimensions, Twilight Forest, Blue Skies, The Aether, Everbright/Everdawn, The Undergarden, Bumblezone, Tropicraft, Gaia Dimension, The Midnight, and the planets and orbits from Ad Astra. Server administrators can also add custom dimension names through the configuration.

While the server is stopped, the .nbt files of stored pets can be edited directly. Changes are preserved and applied to the entity the next time the server starts.
