No way! I honestly don't mind pets dying of old age only. Starvation and fire just seem too unethical to me. I don't think it should be realistic that way at all. That's just crossing the line right there. (This is coming from an animal lover, cats mainly, and a vegetarian, but still). Losing a pet in the real world is devastating, especially with unnatural causes, and I would never want my Sims to go through the same thing. Animals could starve in the original "Unleashed" but Unleashed was more about animals in general, as appose to pets. I barely remember TS1 though.
