Does every cheese have rennet can you give me a list of which ones have rennet and which one dont and places where we can get non rennet ones?

Not every cheese contains rennet; many cheeses are made using vegetarian or microbial alternatives. Common cheeses that typically contain animal rennet include traditional Parmigiano-Reggiano, Gouda, and many aged cheddars. In contrast, cheeses like mozzarella, ricotta, and certain varieties of feta can often be made without rennet. You can find non-rennet cheeses at specialty grocery stores, health food stores, and online retailers that focus on vegetarian or vegan products.
