I'm also a PETA member but I really don't agree with everything that they do, sometimes I think they go a little too overboard. As for feeding my cats a vegetarian or vegan diet I would never do it. It's ok for me, but that was my personal choice, me as a human decided that I would not consume animal products. But as for my cats they are different , and they can't survive without taurine. There are some vegetarian cat foods on the market but I don't really trust them. I've read a lot on the subject and learned that if you really want to give a cat a good and healthy vegetarian diet you need to personally cook their own meals... well I don't even cook my own meals so I don't exactly have time to cook meals for my cats so that I can ensure that they get everything they need. So they will consume non vegetarian foods because I think for their own health that is our (mine and theirs) best option.
