I currently have my soon-to-be 7yr old cat in raw & canned diet (50/50...hopefully 100% raw soon). I'm feeding him radcat as my local store has it and I've heard wonderful reviews about it. My problem is that the containers doesn't seem to be tight enough to prevent freezer burns. In fact they don't seem to be that durable because I've seen some cracked ones in the store. And my cat seems to turn it's nose up on the parts that have been burnt. So I'm wondering what type of tupperware do you guys use to prevent that / how do you guys deal with it?
