What? They're flying rats.
Ironbite-hell I'll pounce and eat them.
They have bad meat. Also, what's wrong with rats? Rats are so cute.
Pigeons are probably toxic, due to the kinds of things they eat in urban environments (so yeah, bad meat).
PET rats are just fine, but the wild ones? I never ever want to see them again. Or wild mice, for that matter. Shitty rental houses and poorly-managed apartment complexes will turn you against the disease-ridden little monsters faster than anything, I guarantee it. Luckily that sort of thing is no longer a problem for me.
