Re: How long do horses live?

@sheridanhoughtonHorse Lifespans
Like all Sims, Horses have a lifespan. On the Normal Lifespan, Foals will take eight days to age up in to an Adult. This is a great advantage if you're planning on raising a race horse because Foals can get a head-start on their Temperament Skill.

An Adult horse has a whopping 50 days before they reach the Elder life stage.

elders for seventeen days, then they will die.  <<< Source:  How Long Do Elder Dogs Live Sims 4 - BikeHike

Tho' listed DOGS it includes HORSE info. The days however, do not match up exactly on all references I found. Seems they can be plus or minus a few.
