Most of them don't have opossible thumbs and there can't work most of the machinery and tools needed to manufacture food.

Why can't an automobile walk. ANS:
Because it was not designed to walk.
most Animals are a part of a food chain. Animals have no need to manufacture food, because each one has the means of obtaining food. it is all already manufactured for them. If they are predators, they kill other animals to eat. If they are herbivores, they live on plant life. No need to manufacture what is already there waiting for them.

Because one of the criteria for being in the Kingdom Animalia is that you must be heterotrophic. If an organism is autotrophic, meaning it can manufacture its own "food", it must be in the Kingdom Planta, Bacteria or Protista. Most autotrophs use photosynthesis to turn light energy into the chemical energy that we call "food". However, some autotrophs use chemosynthesis to turn one chemical form of energy (e.g. hydrogen sulfide) into another, more usable form.
Disclaimer: I studied biology when there were only 5 kingdoms. I think that number might be up to 7 or more by now. However, Kingdom Animalia is still entirely heterotrophic.

Well they manufacture live animals into it's food. Besides, we don't give them their props. Some harvest food, they have to preserve it somehow, spiders keep their food on hold till they're ready, dogs bury bones.
All creatures have their own way on surviving and.....manufacturing.

Animals that nurse their young produce their own food for their young and some animals have to live off their own fat to survive. Like humans, if we were in a survival mode our bodies would compensate and use fat first then use muscle in order to let us live. Animals do much the same. Unless there is an abundance of food then animals don't have to live off their own bodies fat and muscle. Hence the fat.

Let me ask my pussycat, Oscar..
Oscar? A question was asked on YA, you know the internet thing you have your blog on and you and I often answer questions, and they want to know why animals can't manufacture their own food. Do you know why?
Well of course, big daddy, it's because we don't have prehensil digits so it is hard to do it. Any other stupid person's questions?
No, that will do, son, now time for beddy-bye.
So question asker, I think you got your answer.

>Animals manufacture food for plants and eventually become food for plants. In the meantime they eat plants (or other animals that eat plants). It's a cycle of life...Nature is rather fond of cycles.<

probably something to do with evolution. some species probably 'decided' that it's better to eat other things for food rather than make its own- less time consuming

Mammals do (milk), but they still require a net input of other foods.
