You borrow a horse and the owner dies during your ride

Oh, bad news! I just posted in another thread, but removed my quote when seeing this thread.

I was suggesting that horses are household members, asking whether someone checked what happens if the sim(s) of a lot dies. I hoped the horses would stay as a household, and that we'd have our "community lot" stable, as we would be able to visit and "borrow" horses without needing to bother with sims living on that lot. I now see they would probably get culled. I'm having a couple training grounds where just a single sim resides a residential lot, it works fine as a "borrow those horses ground" though, like we already know :)
