Is it okay to buy frozen / thawed feeders from PetCo? I ordered from Big Cheese Rodents but they came thawed and unusable due to weather and a shipping error. Now in a pinch to feed my snakes and want to make sure it is okay.

I saw an old thread on this but it was 1) very old and 2) turned into a discussion about euthanizing live animals and not about the quality of frozen feeders at PetCo and whether they are okay to feed to your snakes.
