The saddest moment for me was when the first dog I’ve made after getting the cats and dogs expansion died, the way pets die in Sims 4 is so sad compared to 3, they just lie down and get reaped while sims cry around them. It was made sadder because the moodlette given to one of my sims was titled “bark no more”, and I couldn’t help but get teary eyed because I could relate on a personal level. I wouldn’t have gotten sad at all if I didn’t feel a connection to the dog, but the pets in Sims 4 I think are really well done in that aspect.
