If you are looking for an expansion for The Sims 3 with a high content hug, then Beestenbende definitely recommended. This extension contains the familiar pets like a dog and a cat more.
In the previous Sims series (Sims 1 & Sims 2) came fluffige beasts already over. But in the PC / Mac version of Beestenbende are also horses. Even small animals like spiders or a turtle, you can lose in a terrarium.
