Catnip
Catnip is a specialized PaperMC plugin designed to enhance cat behavior and introduce a comprehensive bonding system between players and their tamed cats.
Features
🐾 Bonding System
Catnip introduces a persistent bonding mechanic for tamed cats. Bonding levels influence cat behavior and can be tracked by players.
Bond Increases
Players can improve their bond with their cats through positive interactions, such as feeding or playing with them.Bond Decreases
Hitting a tamed cat results in a significant reduction in the bonding level.Bond Decay
Bonding levels naturally decrease over time if a cat is neglected for extended periods.

Catnip introduces several custom goals and behaviors for tamed cats:
Hugging
Cats with high bonding levels (85% or higher) may occasionally approach their owner to hug them, accompanied by purring sounds and heart particles.Play Fighting
Cats with low bonding levels (below 35%) may engage in playful fights with their owner, involving minor damage and hissing sounds.Item Interaction
Cats actively play with dropped items, specifically:- String
- Fish (Cod and Salmon)
Environmental Interaction
Cats may choose to sit on warm blocks, such as:- Furnaces
