I've never tried animal blood, haven't found a way to make it safe, and I only like fresh. The only way I was able to get it was from cutting myself. I'm in a city that has clubs now that some people participate in 'vampirism' in, but common courtesy is you get theirs, they get yours. I'd still have to hide the marks so that is out (even though some more dedicated can draw blood with a syringe). That still doesn't get rid of the safety risks. It's kind of like for someone who likes to be promiscuous. There's no guarantee they don't have some STD or something (since mot of those can be passed through blood. I thought about paying someone to cut and let me drink it (likely prostitute) but still safety risks.
