Immortal Kitty
I'm a dog person, and all of my Sims are as well. But a good while ago, my newest attempt at a Legacy family had the only cat my Sims game has ever had. The cat didn't age and seemed immune to being taken away. She starved, sitting at completely empty hunger for two days, and still lived and stayed there. She's still alive after quite a few generations (as is the founder; she's on a regimen of youth elixir). So the newest generation is living with their great-great-great-grandmother and their immortal cat. Has anybody else experienced anything like this?
