Well i got my order from big cheese today, lets just say i am impressed, great packaging, came in a box with insulation and a block of dry ice, i ordered a pack of pups, smalls, and mediums, all the rats looked great. They came in airtight packaging, and still frozen stiff, had not even began to think about thawing!!! I haven't used any yet but so far i am happy with my order, i only have three snakes, and they each eat a diffident size rat, but, my only source for these size rats is going out of business at the end of the month. Definitely recommend them as of this point!!!
