Bunny

Bunnies or rabbits are a type of NPC animal introduced in The Sims: Unleashed and later returned in The Sims 4: Cottage Living.

The Sims : Unleashed
In The Sims: Unleashed, rabbits are NPC pests that will eat Sims' carrot plants. Buying windmills and scarecrows can reduce the chances of them appearing however. Sims can also have a cat which will hunt rabbits.

The Sims 4: Cottage Living
In The Sims 4: Cottage Living, bunnies live in the wild and act as NPCs. However, when befriended by Sims, they can form relationships, help in the garden, and give gifts. If Sims wish to befriend more bunnies or have them close by, rabbit holes can be placed on the lot to attract more of them. Sims can also name their bunnies and make clothes for them. Lots with the Wild Foxes challenge, will spawn foxes that can be a danger to bunnies if left unprotected by a llama or a Sim.
