This is kinda off topic....but i've been around some BIG local rat colonies....and its just nasty...before you get within 10 feet you can smell that noxious scent of rat urine(i guess?)

i guess when you've got a huge colony its hard to keep it smelling good. but i'll say one thing...i'd rather waste my money buying feeders, than stink up my house by trying to do it myself, lolol
