As a newbie, I guess I don't understand the reason to keep breeding spiders if they end up with neurological problems, no matter how minute. No offense to anyone. I learned with breeding fish, rabbits, and rats that some genes just weren't wise to pass. Like hairless rabbits. They look cool (if you're into hairless animals like I am), but they live short and miserable lives usual. Hairless guinea pigs, on the other hand, only suffer from scratches, dry skin, and getting cold more easily. All very easy to control. Neurological stuff is scary territory.
As for feeding my group, I was thinking about starting with live pinkie mice just to see if they want to eat. I'd rather have to deal with live pinkies than try to explain to hide frozen animals in the freezer. I'm going to have to pick up a little stand alone fridge/freezer (dorm size) when I can.
