you'll get the same from Petco or even worse...I get most of mine there right now till my colony I just set up starts producing well, and I have to search through the bags of the Gourmet Rodent products that they have to make sure that:
1. the bags are sealed ---- so many have come ripped, or with holes in
2. The right number missing --- I kept getting 3 packs with only 2 pinkies in them
3. That they aren't frozen all in one lump --- I am certain they didn't come from Gourmet Rodent that way, they had to have been thawed at least a little and then refrozen that they stick together in one frozen lump.
I have to laugh at my local petstore because they just keep refilling the frozen bag they keep there and in the bottom there are all these little legs and tails.
