Several pets can follow a player at once. If multiple pets are present they will all obey the same order together. Pets that are following you will target a monster if monster hits you or is attacking the pet. If a pet is in your way, re-issuing the 'come' command will generally move him. The command ' come' will make the pet follow you if it was told to stay and will make the pet teleport to where you are standing. They will still defend themselves if attacked directly. Pets won't join fights or defend you from mobs if they are told to stay. The command ' stay' will make the pet stand where it was told to and stop following their owner, though they will pace around a small area and can wander off if their loyalty gets too low. For the commands to work, the pet must be in the same 'screen' as the player. The words must be written exactly that way. They must be done using area ('local') chat by either saying ' stay' or ' come'. To command your faithful pet, two simple commands can be issued. Pets can also be given Costumes to look like some creatures in the game.

If the pet decides to stay on that tile for more than 1 second, it will usually consume the food and say 'arf!' or 'meow' which means that you are now a proud owner of the pet! To tame a pet after you found one, simply drop any type of food (Old Salmonberry, Black Pepper, Honey, Spicy Tea, Raw Meat, Old Cooked Fish) one at a time onto the floor around the pet and wait until it walks over the food. Dogs and Cats can be found in the Underworldrandomly throughout all levels or in Deep Cave, and have a chance of spawning from an Altar. Dogs and Cats (aka 'pets' or 'critters') are mobs that can be tamed to follow and fight for their owner.
