A vegan does not consume animal products of any kind, including meat, poultry, fish, dairy, eggs, honey, gelatin, or even white sugar, which is typically processed using animal bone. Most vegans avoid wearing leather, fur, wool, cashmere, felt, down, mohair, and silk because of the pain and death linked to animal-based fiber industries. Also Vegan's try to stay away from buying products from company's who preform animal testing.
Friend 1: Hey dude. Albertsons has a sale on Iams.
Vegan: Sorry, Can't buy it...they test on animals.
