Pets are a type of highly interactive boys that can be bought by a player in the hotel. They were first introduced back in 2002, but the only pets available were dogs and cats until 2007, when Crocodiles were introduced. They didn't come with many features; they reacted to certain chat commands and ran to the owner whenever they entered the room. Players are now able to interact with all pets, whether it's scratching them or training them. They vary in price and cannot be traded or recycled in the Ecotron. Over time, more and more pets have been released, from Dragon, Frog and Spider right through to the slightly less plausible Pet Leprechaun.
Before any pet is bought, the player is given the option of changing its name and colour. There is a wide range of colours for every pet, but they cannot be changed after the pet has been bought - unless it is a horse, which can be dyed. Each pet comes with 'Starter Food', but as Starter Food is low in energy, many players choose to buy other accessories to keep their pets happy, including a water bowl, food, bed and toys. Each pet has different accessories and they can cost anything from 1 to 6 credits, with food available in bulk packets and pixel substitutes. Pets do not die without food or water, but will be unable to train until they have replenished their energy supply.
