How long can a horse last without eating?
A horse can go without eating for roughly 8 days, but by the second day the horse will have already started to deteriorate in condition and health.
When left to their own devices or in the wild, the horse will spend about eight to sixteen hours a day eating grass, since grass has such little energy and they need to be able to run for a long time without eating. But in captivity, of course, they only eat as long as it takes to finish the food they have been given.
I suggest that you do not rely on a public sharing and editing informational website that may contain false information for your turtle's starvation rates. 'How long a turtle go without eating?' How long can YOU go without eating? 1?2?3?4 hours? Maybe even 5? Don't take the risks, for it is a living being too.
