Raccoon

The Sims 3: Pets
Raccoons appear wandering in the player's home neighborhood following the installation of The Sims 3: Pets. A Sim can either 'watch', or 'shoo' the raccoon, although some Sims may be able to 'pet' them. Raccoons can often be seen tipping over garbage bins on residential lots. Watching raccoons raises a Sim's hidden Wildlife skill.

Trivia

 * Male raccoons are always named 'Meeko', female raccoons are always 'Meeka'. However, on mouseover, they simply say "Raccoon".
 * Sims may have a wish to watch or pet a raccoon.
 * Raccoons are actually reskinned cats.
 * When raccoons meet Sims with a high wildlife skill they will sometimes autonomously ask the Sim to play "chase", the same game cats can request of Sims. This cannot be requested by the active Sim, only the raccoon can initiate it, making it a rare interaction.
