Xantho's Shrink System
The Shrink System allows pets to be shrunken to small statuettes that can be carried in a player's backpack. This can be done using a few items inside the game. A Pet Leash, an Enchanted Pet Leash, Pet Shrink Potions or a Hitching Post. This is an alternative way to using stables as you can shrink pets almost anywhere in the game.
