Planet Zoo 2 enrichment list for every animal — food-based and habitat items
Enrichment is the part of welfare the game never summarises: each species accepts a specific set of food toys and habitat items, and anything not on its list does nothing for its welfare score. This is the full mapping from the Zoopedia, all 136 species, with the item lists behind each count.

If you are furnishing a mixed habitat, these are the items that satisfy the most animals at once. Note that the cheap universal winners are also the ones with the smallest welfare contribution — a mud bath keeps a lot of species happy, but the high-value items are usually group-specific.
How enrichment interacts with welfare
Welfare in Planet Zoo 2 is a composite of space, social group, temperature, terrain mix and enrichment coverage. Enrichment is the only one of those you can fix after the habitat is built, which makes this page the practical one: place the items on the species' list, then check the welfare panel rather than guessing. Pair it with the care values table for space and temperature, and the social needs page for group size.
Questions
What enrichment does each Planet Zoo 2 animal need?
The Zoopedia lists two categories per species: food-based enrichments and habitat enrichments. 105 species have at least one food-based item and 84 have at least one habitat item. The table above is the full mapping — open the item count to see the list.
Which enrichment item is used by the most species?
Small Ball, listed for 32 species, followed by Mud Bath (25) and Rubbing Pillar (24). Items are not interchangeable: a species only scores welfare from items on its own list.
Why do 31 species have no enrichment at all?
They are exhibit animals. Insects, small reptiles, amphibians and a handful of fish live in a glass exhibit rather than a habitat, so the habitat enrichment system does not apply: Amazonian Giant Centipede, American Bullfrog, Axolotl, Boa Constrictor, Cloudless Sulphur, Common Bluetongue, Danube Crested Newt, Desert Horned Viper, Diamondback Terrapin, Eastern Brown Snake.
