Humane way to euthanize rats?

[satomi325]

sometimes i get deals on 50-100+ live rats. i take 2 5 gallon buckets and fill them half way with water put some rats in one and put the other on top. then just dry them off and freeze them. not something i like to do and can be a pain in the a$$ doing 100 rats but it works.
anyone use the dry ice way mentioned above? and where do you get dry ice?

You can get dry ice at many grocery stores and super walmarts. I highly recommend CO2 euthanasia for you.....Freezing is not humane at all and very painful. If you can't get dry ice, you can use vinegar and baking soda instead.
