I wouldn’t ‘feed’ them at all. I don’t feed any of my Nepenthes or other carnivorous plants. They catch their own food, that’s what they’re made for. But if you see that for a long time (months) the pitchers have been empty, then you can catch live prey (insects) for them. They don’t need a lot of food, and they don’t need it all that often.
I advise against using meat or anything like. It’s not optimal for them in terms of nutrients and mostly it will just result in a rotting and dead pitcher.
I want to mount a light on the patio fence that is the same temperature as the mushroom light in the purple and white flowers. One along the sidewalk path to the door and two on the inside of the fence where the ground cover is located.
