|Joja Co. patented technology for coops and barns. Keeps your animals content, but can't replace the full benefit of human touch. Hand-petting can be provided to supplement.
The Auto-Petter is a tool used to automatically pet barn and coop animals every day. It can be purchased from JojaMart for 50,000g after completing the Joja Community Development Form. It can also be found in Skull Cavern treasure chests. Additionally, it can be obtained by killing monsters or breaking crates/barrels as a special item in The Mines during the Danger In The Deep quest or after activating the Shrine of Challenge.
Auto-Petters can be placed anywhere, but will not do anything unless placed inside a barn or coop. To remove an Auto-Petter, it must be struck with a tool or by repeated left-clicking.
Auto-Petters cannot be sold or deconstructed.
The Auto-Petter will prevent animals from losing Friendship or Mood due to lack of petting and animals will gain approximately the same Mood boost compared to manually petting. However, they will only gain 7 pts (approximately half the normal Friendship points) from petting this way. Happiness gain from an autopetter stacks with manual, but friendship gain doesn't. 
- See FarmAnimal.pet in the game code.

- 1.5.1: Fixed crash that could occur overnight when placing the Auto-Petter in an area that isn't a Coop or a Barn.
