I was in Target Store the other day and saw a freezer case with raw dog/cat food for sale in small quantities. Raw feed is becoming more popular with all the dog food recalls in the last few years and availability is really starting to increase. I even received a flyer the other day from a company that will home deliver cases of frozen food.
You don't say what size animal your feeding so it is a little difficult to offer advice, But, consider a small portable freezer. Use a hand hack saw to cut the frozen packs into smaller portions
to thaw. Check with a local butcher shop and see if they will saw it for you at the end of the day before clean-up. Thaw the larger pack and repackage in smaller portions and refreeze.
Feeding raw takes a lot more effort and planning then just dumping kibble into a bowl. Most people that start it will drop it within the first few months for various reasons but it usually boils down to
"too much trouble"
Good luck
