The process of making cheese is to have it curdled with an enzyme called rennet with occurs in animal stomachs naturally. Vegetarian cheese is made with vegetable rennet, fungi or bacteria. To be able to spot the difference between vegetarian cheese and animal rennet cheese is almost impossible unless its marked vegetarian cheese in the store, so watch your vegetarian foods.

The vegetarians that don't eat cheese with animal rennet do so because they believe it causes animals to suffer when being slaughtered to extract the enzyme. Without the properly labeled product a ethically opposed vegetarian has a very hard time in distinguishing it from cheeses that were curdled with plants.

The vegan will not eat cheese at all because cheese is a byproduct of an animal. Many vegans will eat a product called chreese which is a non-soy, natural cheese replacement. This chreese is just one replacement of many. Just go to your local health food store or a organic store and there will be other vegetarian food products to choose from.

If you have being eating cheese and you are a vegetarian you may wish to change your dietary habits. Cheese made with animal rennet may have caused some animal suffering. So you have like three choices, buy cheese alternatives at a health/organic store, purchase vegetarian cheese online and/or look for the label on the cheese that says vegetarian cheese or vegetarian recipe cheese.
