Ant farm

An ant farm is a buyable object in The Sims 2: FreeTime and The Sims 3: Pets. In FreeTime, it is in the Miscellaneous area of the Hobbies section of Buy mode, under the name The Formidable Formicarium, and costs §185. Sims can observe the ants, which builds enthusiasm for the Science hobby. Sims can also shake the ant farm, which may allow the ants to escape.

In The Sims 3: Pets, it can be found in the "Pet accessories" section of buy mode, and costs §100. A Sim can only watch the ant farm as the ants move around in it.
