Forever Pets

Simply makes all tamed cats, wolves and parrots completely immortal.
Even /kill won’t kill them.

If you are playing multiplayer, you only need the mod on your server.

If you already have tamed pets, they will become immortal once you install the mod.

How do I undo this?

The only way is to uninstall the mod. After this, your previously tamed pets would still be safe from environmental damage, but player damage or commands would hurt/kill them. Think twice!

Any disadvantages?

This mod breaks game balance, because your immortal wolves would still attack hostile mobs. Also, only cats, wolves and parrots are supported.

Try Invincible Pets, if you want:

• to choose which pets to make immortal
• a larger list of supported pets
• an undo feature
• immortal pets not attacking hostile mobs
