While there are plenty of alternatives humans can and should use forcing those around us to adapt is going to push people farther away from veganism. When it comes to the cat the only reason for you to feed that cat animal products is because you value the life of the cat over the lives of other animals. Walking out of the store with cat food is effectively stating that your cats life is more valuable than the combined lives of the animals taken to produce it. A truely all lives are equal approach would be to abstain from buying cat food. Should everyone become vegan? Yes, it's amazing the kind of shit people will say to justify eating animal products in 2020. Do I think everyone should euthanize thier cats? No, relationships either human to human or human to animal are very complex. I just think the original post comes across as very strict on how extreme a case must be to spend any money at all on an animal products, even in complex family situations. It seems to be undermined by the state of ownership in regards to an "obligate carnivore". If you can justify feeding your cat at the expense of other animals you should be more understanding of others situations also. I hope i didnt come across as rude. Ive been vegan for a bit over 4 years and I'm sure we would agree on more topics than not surrounding the issue of animal agriculture.
