I have gotten this bug recently and I'm unsure of what would be causing it. My sim dog, Betty just refuses to eat on her own even if she's starving. The only solution I've found so far is having my sims constantly call her to eat, which I find very annoying. If anyone could help me with this problem, I'd appreciate it <3
Are you using any mods or cc in your game? Try to remove them and see if the game works better.
For example, move the mods folder from C:\Users\Username\Documents\Electronic Arts\The Sims 4 to your Desktop and start the game.
You could also try repairing your game (with mods removed)
Open your Origin client and go to My Game Library, right-click The Sims 4 and choose Repair.
Does she never eat or just sometimes? I do get the notification sometimes that my pet is starving, like they forgot in which room the bowl was.
Does it depend on where she is on the lot?
