Fish on a Leash!
Manage your leashable entities! Choose which mobs can be put on a lead.
About this Mod
This simple mod will allow you to use a lead on mobs that are normally not leashable in vanilla Minecraft.
To enable or disable which mobs can be leashed, edit the config file directly or use Mod Menu. Beware that it takes a restart for changes to take effect.
All included mobs can be put on leads by default, except Villagers, Illagers, and Witches.
Please note that for the best experience possible on servers, the client configuration should match the exact server configuration (configure it by editing the "fish_on_a_leash.json" file located at the "config" folder inside your server's directory). If this mod is not installed and configured on both client and server sides, some mobs will stay unleashable.
