Vegans do not eat or use anything that was once part of an animal’s body, which means that not only do they avoid eating meat, eggs and drinking milk, but they don’t even wear leather products or use cosmetics tested on animals. But even when they are diligent, they may run into unexpected surprises, as one can easily encounter an animal-based product when least expecting it.
Tattoos and chewing gum may not be vegan. Animal-based products are used even in the making of seemingly harmless drinks. And what about condoms? They can be non-vegan as well. You may even need to watch out for money!
