Question

in the world Tiger eat all parents of their prey including bones in their develop born problem when they are read only flesh​

Answer 1

We fed our tigers all parts of the animal they were eating, not just the flesh. You need the bones, muscle, sinew, skin everything. Bones are particularly important because they are a great source of calcium. You will get problems if you only feed them the tasty morsels.

With all animals you must try and simulate what they get in the wild as that is what their bodies are used to.
