I have put about 500 rats into the freezer so far. My first bunch I packed into freezer bags, 3-4 per bag, with most of the air pushed out. My latest bunch Ive been individually sealing in vacuum packed freezer storage (seal a meal type thing).

I'm just wondering how much longer rats keep when vacuum packed compared to just in ziploc freezer bags. I know Ive ordered pinks/fuzzies from a few different places and they all came in normal freezer bags.

I figure that it costs about 10-13 cents per large rat with the vacuum pack method, and pennies when using zip loc.

Any input is appreciated.

Edit: For those who vac pack, do you pre-freeze them partway first? I've been using the gentle vacuum but there is still a little leaking from the nose/ears when vacuuming them freshly killed.
