Fifi Died

I just turned aging back on and played for a while and there are deaths. Got a message that Fifi died and did I want her inventory to go back to her last family. Said yes of course. But I'm 99% sure Fifi was someone's pet and the only things that could be in her inventory were gifts for her owner or spare dog/cat collars. Can't remember who owned Fifi but had to be a pet as no sims of mine would be named Fifi.
