I handle - but not cook - raw meat for my cats. All three of them eat a 100% raw meat diet.
How do I justify this in my mind? I find it difficult. I would love for them to be on a vegan diet, but I have done the research, and I haven't yet found anything that proves to me conclusively that they will thrive on one. I believe cats are obligate carnivores, and thus I have no choice in the matter. They are entirely indoor cats (pretty much a necessity, since we live in a high-rise apartment complex in the Docklands), and I would prefer to prepare meat for them than have them go out and kill birds or other animals that are fast being extinct - although that isn't my only reason by far for making them indoor cats. I believe it it a different matter with dogs, and, if I had a dog, I would have a decent attempt at feeding it a vegan diet, at the very least.
Other than that, my house is completely meat-free. We do make an attempt to source meat that has lived a fairly good life, but at the end of the day, it's still dead flesh, and that comes with it its own ethical dilemmas. I find it difficult to handle myself, and I have been known to ask my partner to do it instead on more than one occasion.
I would never cook meat for any human, though. Ever. I don't think I could live with someone who consumes meat, either, now that I am independent, and haven't lived with a meat-eater since 2008.
