Mate, you can absolutely eat fresh killed meat. There’s whole chunks of cuisine based around it. Heard of sushi, blue steak and steak tartare?
You’ve already got half the answer in your question. A ‘fresh kill’.
The meat most humans eat isn’t exactly fresh, not as fresh as a predator’s kill. It’s typically been slaughtered at an abattoir, probably stored for a few days and then shipped out to wherever we buy it, then might spend a few more days in the fridge. It’s several days, if not weeks, old by the time we consume it. That’s a long time for bacteria to grow, especially on something with a high surface area like mince. That’s not a good idea to eat uncooked.
Bacterial contamination is the main reason we cook our meat, and is a common cause of food poisoning. Carnivorous species can become sick from these bacteria too, but are less likely to as they have a shorter intestinal tract. It is entirely possible for a dog or cat to suffer from Salmonella or Campylobacter.
There are other reasons we cook our meat too - parasites being the big one. Tapeworms and Toxoplasma are transmitted in uncooked meat, and other animals will absolutely be infected by them. They’re just not usually particularly noxious in their intended host.
