i ran into that problem when looking around for a feeder rat supplier. i called petsmart and petco to get their prices and when a guy answered at petsmart i said "hi i was calling to find out what your prices are for live feeder rats?"
and i got this snappy response...
"[tone of shock and disgust] we dont sell our rats as feeders." and then the guy proceeded to lecture me on his moral beliefs on
"...feeding animals to other animals."
yes he actually said that bit.
i was polite and quietly listened to him ramble on for a while but when he said those words my patience with him had run out and i was not appreciating his condescending tone.
i asked him if he was a vegetarian and when he said
"psh! no. what's that got to do with anything?"
i said "cuz if you dont believe in animals being fed to other animals then how the hell can you sleep at night knowing some poor little cows, chickens and pigs got chopped up to fill your freezer?!"
he had the balls to gasp then i hung up on him before he could pick his jaw up off the floor and argue with me.
i got the "we dont sell our rats as feeders." response at petco too but that person hung up pretty darn quick after saying that.
whatever.
i found a hole in the wall pet store that sells feeder rats and mice and for a little bit there the guys were good about understanding my need to buy the smallest of their smalls when i provided the explanation that my bp wont eat anything bigger even though i know she can. now though, i'm feeling a little bit of impatience from them. i dunno, maybe i'm imagining it but i swear i think they're getting tired of showing me different sizes. it's not my fault though, i have to go with what my snake will eat, simple as that.
