Social groups and per-sex caps

Every species record publishes a mixed group range and, where relevant, a cap per sex. The cap is usually what breaks first after a litter.

Social welfare is checked per animal. Overstocking does not show up as a habitat failure — it shows up as one animal being outside the group limit, which then flags the group.

Release a pair first: it is easier to stay inside both limits while welfare stabilises.
Check the per-sex cap before breeding — a litter can exceed it in one cycle.
Neutral and thriving companion species are listed per animal; mixing without checking is the second most common mistake.
Shoal species carry their own welfare rules (1.0.4 adjusted shoal welfare).
