If you do a web search for ["vegan condoms"](https://duckduckgo.com/?q=vegan%20condoms&t=hb&ia=web) (yes, vegans use exotic and conscious search engines..) you will find that **cruelty-free prophylactics** are an item that is being sold. However, how could a common condom be not vegan? Is there any ingredient that comes from animals? Or any ingredient that is tested on animals?
