does your pet have an unhealthy obsession with a fireplace in your sims home?
asking because I had an issue with pets where they wouldn't eat unless told and wouldn't pee outside unless told (even though they already learned how). they would whimper and all that stuff. I discovered that it was an obsession with the fireplace that was queue stomping both of those things causing the actions to be cancelled every time. I turned off the fireplace and the issue went away, this made me remove all the fireplaces in homes where pets had a fireplace obsession. granted this was a month ago, so might not help you, but thought it might be worth mentioning.
