There is actually adequate scientific evidence that many animals have a much greater awareness and emotional intelligence then we often attribute to them, this includes most if not all of our domesticated animals. You could argue that the act of meat eating isn't in itself amoral, but the mass suffering facilitated by the conditions within the meat industry certainly is. Not to mention the conditions it subjects its workers to. There is no ethical industrialized meat consumption.

do you think non-human animals dont feel pain

Recognizing the capacity of animals to understand and suffer is basic science, not idealism. People with pets understand this and we know they should protect the health and well-being of the animals they keep. In fact, they often support laws requiring that pets are treated well enough.

But the moment it's a designated food animal, this goes out the window and brains shut off.

So anyways are you gonna eat dogs and cats or are you an "idealist"?
