As briefly mentioned in the Maxoid blogs already, EA has released a patch for the Body Shop version in The Sims 2 Pets for PC. A compatibility issue made the program incompatible with content created with earlier versions of the Body Shop. The issue has now been solved, and a fix can be found through the news page.

Besides that a patch that will solve gameplay issues with Pets will be released soon. This patch was announced in a message sent to all members of the official site. It'll be released early this year, though it's not sure when exactly it'll be out. When it is, we'll let you know.
