@Kita5399 What a surprise considering the familiars have different functions than regular pets. That's a head scratcher for sure. LOL I hope it continues to work for you! My new avatar is Ringo, the main cat I test with. I have been successful in keeping him from disappearing for over a hundred hours at times. Then there are days he will disappear one to three times. I still have all the Eco options turned off but I did enable the rain and thunder storms again but he hasn't gone MIA during a storm so that was crossed off the list of reasons why the pets disappear. I did change one of his traits to Aloof so he often runs around the neighborhood on his own but always returns. And as I was following him I noticed whenever he runs past a rat it will squeek, which kinda made me laugh.
