I killed them and ate their livers...

I recently found out that one of the old Sonic game manuals (I don't know which one) supposedly claimed that Fang the Sniper's favorite food is roast beef. But the only animals in Mobius are anthros, right? So does that mean when Fang wants his supper he goes out, murders a cow and cannibalizes it? O_o
In one of the old Knuckles the Echidna comics, it is strongly implied that the "good guy" carnivores (Vector the Crocodile was the example) supplement with tofu. That works for the good guys, but I cannot see a ruthless, child-shooting villain like Fang walking into a health food store and buying tofu...or even holding up a heath food store and stealing tofu. So where do the carnivorous villains get their meat?
