Excuse me if i've read your post incorrectly ?
You bought a corn from petco, and after 2 weeks of non feeding, and petco refusing to refund/replace the corn you decided to put it in your freezer ?
$500 insurance is not required, all you needed to do was ask for a bit of advice here.
tease feeding/assist feeding would have probably sorted out the issue, but instead you chose to euthanise.
Hmmmmmmmmmmmmmmmmmmmmmmm
Did i miss something ?
