How do predators avoid becoming ill in cholera, diarrhoea, dysentery and similar diseases?

They aren't exactly careful when eating a kill, especially pack animals where there can be quite a fight over a catch and, I assume, should regularly get pieces of the large intestine in their mouth - which should be very unhealthy, shouldn't it?

Even house cats, when they eat mice and rats, seems to swallow them more or less whole and then cast up the skeleton = all contents of their prey's intestine remains in their stomach.

    $\begingroup$ They’ve evolved and adapted to be able to eat what they do without getting ill (although they probably do get ill from eating bad food on occasions) because of natural selection. Remember, humans are quite different to other animals and what makes us ill doesn’t make most other animals ill. $\endgroup$

    $\begingroup$ Pet owners might disagree with you that their fluffy predators do indeed avoid food poisoning. $\endgroup$

  • $\begingroup$ @BryanKrause - I immediately thought about my dogs when I read the title of this question. Luckily, the three I have right now have GI systems of steel, but some of my previous dogs... did not. $\endgroup$ Commented Jan 31, 2022 at 20:29

    $\begingroup$ Not only "should [they] regularly get pieces of the large intestine in their mouth", but when I lived on my farm(ette) in the woods, where individuals were allowed to hunt, the dogs would go looking for guts to eat. We took to requiring every hunter to bury the deer's innards. The dogs would come back covered in dirt with guts to eat. We then took to requiring burial of innards with rocks stacked on the site. The end results of enjoying the contents of small and large intestines were unpleasant, to say the least. $\endgroup$ Commented Jan 31, 2022 at 20:35
  • $\begingroup$ Eating the meat freshly killed helps rather than letting it fester in the fridge for a week before eating it. $\endgroup$
