Right.
Is this page easier? http://www.modthesims.info/wiki.php?title=Game_Help:Installing_Sims_3_Package_Files/Setup_and_Files
1. Make sure your game is patched. It probably is since you've got pets...
2. Download the framework (the 'mods' folder) and extract it and then place it in your 'documents/electronic arts/the sims 3/' folder. Then put my file in the 'documents/electronic arts/the sims 3/mods/packages/' folder.
3. Delete the cache files from your 'documents/electronic arts/the sims 3/' folder(Here they are: http://sims3.crinrict.com/en/2011/01/faq-delete-your-cache-files.html Very useful page)
4. Start your game and test it.
5. I hope it works. :P
