There is a reason not many people are vegetarian. It is a luxury.

Some bend-over is fine by me. Ban peanuts from school, whatever. They won't add much anyway. Have some gluten-free bread. Not every kid needs to drink milk. Don't plant flowers that attract bees, wasps etc... at public spaces. Have some "epi-whatever" medicine at schools just in case. Such is reasonable. They won't cost much.

Don't you think that every food having same basic ingredients is absurd? A bit exaggaretion but stil...

Well, there must be something they can eat.

It is not that of an unreasonable demand. Fat people have their large size brands. Besides, not every food needs eggs in it, for example.

I think there is market for a restaurant which serves specifically for food allergies. Would be expensive, but worth it.

You put a paint or some other patch onto the animal's forehead and show them a mirror. If they realize themselves in the mirror, they will touch themselves in that spot.

Very few animals seem to notice themselves in mirrors. Great apes including humans, elephants, dolphins, some birds and very few fish.

Dogs never pass the test. We tend to humanize them but they are not really smart animals. They seem to have no capacity of conceptualization.

Dogs fail mirror test though.

There was actually a very similar topic of discussion.

Dogs seem to fail it unless trained. Though I see no experimentation like mirror test.

Most animals would not understand that humans are the ones who throw paintballs.

Can wolves understand that?
