OMG CHINCHILLA!!!
When I discovered that TS3 Pets had a Chinchilla I KNEW that I had to figure out a way to extract it for Orikes. I think I've got most of the bugs worked out.
I used this tutorial by Klinny to make the TS3 pet work in TS2. Cage for the pet is a clone of the Wood for Sims guinea pig cage because I've always liked the look of that cage.
The cage comes in five colors - the Chinchilla comes in three. You will need to have both the cage mesh and the pet mesh in your downloads in order for it to work correctly.
The Chinchilla is slightly larger than a wormrat so there are some oddities especially with the feet and tail. It is still smaller than a real Chincilla would be but at it's current size the human animations still show correctly.
