Can't create pet sim with My First Pet Stuff pack
New player on Mac, been playing less than a week on the base game. I purchased My First Pet Stuff pack because I wanted to try to add a pet before spending $50 on Cats & Dogs in case it wasn't for me...
You are unable to create pets such as cats, dogs or horses with the My Pets stuff pack. You need to have the Cats & Dogs pack or the Horse Ranch pack to be able to do that.
With My First Pet pack, you can have a hamster, rat or bubalus, with the cage/habitat item that comes with the pack.This link explains about the pack and the items in it. There are items in it that you can use if you have the Cats & Dogs pack as well.
