Holy macaroni, Ive always wanted a vacuum sealer for food. I am willing to bet it will be $15 plus here in Canada (if I can find it) but heck, I'll go for it if I can! I feed F/T and would love to have one to seal my rats individually so they stay a little more preserved

As for your question of how humane this is to use on mice, I think it sounds o.k (not that I enjoyed imagining it)
