OK, here’s what happened in my 100 Baby Challenge household:
one of my kids got the Competitive trait as a child, and she was Encouraging a Healthy Competitive Spirit with her imaginary friend...
Ideas
Okay, I removed all the CC and mods, started a fresh vanilla game, and created a family to test it.
When the cat was nearby, I had the child perform the Encouraging Healthy Competitive Spirit interaction with her caregiver, and the cat once again became strangely stretched (I even took a close-up shot of it!).
When the screenshot includes the UI, you can also see a “bored” thought bubble floating above the cat’s head.
Basically, the cat stays in this state until another Sim calls it over (I’m not sure if it would move on its own if I just leave it like that).
