There isn't any one test that can tell you whether or not you have Crohn's disease. And Crohn's disease has many possible symptoms that are the same as symptoms for other health problems.

Make a clear diagnosis of Crohn's disease.

Best Answer: Only some animals are territorial. Many animals live in herds or individually, and the herd may move continuously, so there is no territory or even home range for these animals to defend. For example, the great herds of African mammals migrate annually because they run out of food if they stay in one place. So they have to keep moving to find enough food.There are basically two reasons when animals become territorial: 1. survival. Lions and tigers for example defend large territories in order to find enough to eat.
