too expensive.....it's cheaper to buy them from Africa to feed to kings.........yes it happens........
I have a friend with a big pair of kings and he uses free cornsnakes to feed the babies.......(I supply him)...(kinked,non-feeding,and non-sellable corns).....
the adult kings were trained to eat rats.....which is not that hard and they do well on......they are at at least 13 and 11 foot plus now....eat rats with no problems.....
have fun.....
oh.....captive balls I sell for at least $25 wholesale
........you can import them for anwhere from $3 each to $8 depending on who from and when you buy them.........
