Same answer. That's just another part of the problem. Killing them, eating them, or raising them to be killed the problem vegans have is that killing animals for any purpose (sometimes with the exception of clothing) is wrong
one lady on tumblr said all of her cats were vegan, but she had to replace them every couple of months. It doesn't take a genius to figure out that all of those cats died because she wasn't giving them proper treatment. Supply and Demand? No. Mental illness.
