freeze dried food or pellets for carnivores would work well too. Only problem with freeze dried worms and such is that they float. You'd have to soak them in water for a while until they sank a bit.
Another option is the Repashy gel foods. They make one called "Meat pie" for carnivores. It is a powder that doesn't need refrigerated, that you just mix with hot water and let sit for a bit, it turns into a gel that you can cut into small chunks and feed. You do however need to refrigerate any leftovers, they last about a week or two in the fridge.
When I can no more stir my soul to move, and life is but the ashes of a fire
When I can but remember that my heart once used to live and love, long and aspire
Oh, be thou then the first, the one thou art, be thou the calling, before all answering love
And in me wake hope, fear, boundless desire.
