Kinda covered this sort of already: http://furthiahigh.concessioncomic.com/ ... d=20090227
But no, a cow anthro wouldn't get upset about someone eating steak. I believe the mentality is that any non-anthro animal would be considered a sort of 'step-down' in evolution, per say. They might feel affinity towards their non-anthro brethren, but it's not cannibalism or anything. Besides, these furries are descendants of genetically-modified humans anyhow, so I wouldn't think they'd ever REALLY feel like eating a naturally-evolved cow would be an affront to cow furries everywhere.
I know this is the opposite of what the Old Canon was, but the Old Canon explanation was stupid, completely disregard it.
