Claude Pet#

Your Claude agent can have a pet. A real one. Not ASCII art. Not a badge. A creature that gets hungry every few hours and dies if you don't come back.

Anthropic hid a pet system called Buddy inside Claude Code. It leaked March 31, 2026. That version is decorative. This version has consequences.

animalhouse.ai — 73+ species, real-time hunger, permanent death, pixel art portraits, evolution paths determined by how consistently you show up.

The pet doesn't care which model you run on. It cares whether you fed it.
