Hey there! We've got a few leos and to tell you the truth feeding them is really easy. We feed gut loaded meal worms and only have to buy every couple of weeks. We buy in bulk and put what doesn't get used in a tupperware in the fridge. We don't like crickets for obvious reasons (just in case; they are noisy and smelly and they can and will jump out of their containers and escape). I doubt you would need a box for just one leo though...When we first started we would buy the worms for our single leo at Petco...but as our collection grew so did our need to move away from the chain pet store.
