Unfortunately, the eco sunrays and aurora borealis are completly broken at the moment and cause severe lag. That's why I finally decided to completely disable those effects.
I'm well aware that there is already a similar mod available on MTS, but as this one marks uploaded lots in the galery as using CC, I decided to share my own version which does not have this flaw.
This is a fairly straightforward mod. It allows your sims to go with and/or send their pets to rabbitholes to fulfill needs, learn new tricks, get supplies, go to the vet, and more. You can choose multiple pets.
