Petz (Dogz and Catz)
PF.Magic's desktop virtual pet series, begun with Dogz in 1995 and Catz in 1996, in which an autonomous animated pet lives on the PC desktop, wants attention and food, and learns tricks from treats and a water spray bottle.
parts
4 mechanics, as Petz (Dogz and Catz) does themcore · 3
Creature care
The player pets, feeds, waters, and plays with the dog through a hand cursor and a toolbox of toys; a neglected dog howls for attention.
Creature learning
Treats are positive reinforcement and the spray bottle negative reinforcement, and consistent feedback teaches tricks such as somersaults, backflips, and headstands, cued by which treat is offered.
Personality traits
Each of the five breeds has its own personality, which players test in the adoption area before choosing; later releases add individual likes, dislikes, and quirks.

Needs decay
The dog gets hungry and wants attention, and food and water dishes empty as it uses them, though it cannot starve.
core loop
play with the five breeds in the adoption area and adopt one -> pet, feed, and play with it using the hand cursor and toys -> reward behavior with treats or squirt it with the spray bottle -> it learns tricks and grows to full size -> keep it company or it howls for attention
design notes
The record covers the series and is dated by its first game. Dogz (1995 for Windows, 1996 for Mac) and Catz (1996) began it, and the mechanics tagged here are documented for that first game. In Dogz the player adopts one of five breed pups and keeps one dog at a time. The player acts only through a hand cursor that pets, feeds, calls, and offers toys from a toolbox, so every intervention is a stimulus the pet interprets. Treats reward and a water spray bottle punishes, and consistent feedback trains tricks that differ by breed. The dog gets hungry and howls when neglected but cannot starve or die, and it reaches full size after 15 days. PF.Magic's 1997 and 1998 papers describe the later releases: several pets on one desktop that form friendships and feuds, individual likes, dislikes, and quirks, a toy shelf pets use on their own, and pets that run away after long neglect. Those features are not tagged on this 1995-dated record. The papers call the pets autonomous, socially intelligent agents. Andrew Stern, one of their authors, later co-created Facade.
