Is deleting those five files manually really that bothersome?

I don't personally mind it, plus, I get to delete error trap files as well. I really dislike having those in my folder...they stick out with their long names and...error messages. *has nervous ticks* Yes, I'm slightly neurotic when it comes to things that are out of place

As for playing with pets - yes, if you set the adoption of pets to false in NRaas Overwatch, unplayed households will no longer adopt pets. And I use NRaas Register as well to remove strays and wild animals.
