Re: I purchased Sims 4 cats and dogs but it is not showing up on 'My Game library'.

Hi @Gracie_Elliott

have you tried logging out and back in ?

If that still fails, you will probably need to contact a game advisor to check your account

Game advisors can be found through live chat or call-back

In some situations, the older version of Origin installed from the disc may not update correctly. It should be uninstalled with the program add / remove programs and download again
After the Origin installation, click its icon on the right mouse button and select the Run as Administrator option. If this game is not found in the Origin library, you must contact EA's adviser.

However, the same issue with this bundle were already reported on Polish EA Help by two another players what is a little worrying
