I would go check out kingsnake, look for breeders (CBB offspring) and you wont regret it. If you buy from petco most likely its WC and they are a head acke to deal with, very picky and dont settle in that well. I had to buy roaches (dont make noise like crickets and breed quickly) because they wont take meal worms, supers or silk worms and for me that was a little bit of a pain. Go to kingsnake or i will even forward you a few other breeders emails as i have only eggs right now that are going to hatch soon but i keep all until there 3-4 months as they are slow growers compared to leos
