hi i recently after 8months got my mouse eating spider ball to take a mouse scented rat pup.all i did was put the large rat pup that was alittle bigger than an adult mouse in a small tub with four live female mice that i had breeding at the time and let them all crawl n rub all over the pup for about ten minutes supervised of course.then i opened my spiders tub n dangled the little guy above him and he immediatly struck the rat pup!!and ate it and didnt even try to spit it out or anything!!any bp breeders know how big of deal it is for them to eat rats instead of mice and after 8mnths i finally did the trick.hes only 500gms bcuz of his picky feeding but should skyrocket now.sooooo..now my question lol."does anyone know if anyone has made such a thing as a mouse scented spray?"i mean they have all kinds of sprays to attract other types of animals both carnivors and herbivores so why not mice scent for snakes?lol spray the scent on a rat and bingo a big rat that smells like a mouse!!lol
