What the developers say
| Question | Official answer (paraphrased from the pinned FAQ) |
|---|---|
| Do horses die? | No. They retire with age; neglected horses can be removed by animal welfare. Either way they leave the game. |
| How does age work? | In in-game days (rounds), not years or months. |
| Day limit? | None in the full game. The demos are limited to 25 days. |
Achievements that mark the milestones
A Forever Home (a horse moves to the retirement farm) and A Whole Life (a horse you bred retires at your yard) are the two retirement achievements; Empty Nest (own no horse at your farm) is the hidden one you get after selling or losing everything.
