From a hedgehog rescue:
don’t feed calciworms. An excess of calcium is just as harmful as a lack.
Dried insects can also cause bowel impactions which are not good for wild animals whatsoever.
Stick to meaty cat or dog food, dry kitten kibble is a good match with their mouth size, with a meat ingredient listed first not cereal. Higher protein in the analysis is best - definitely over 30% and preferably 35 and up.
Plenty of fresh water at all times. Wet food attracts flies and freezes solid in winter, so dry is often better. If cats are a problem, a cat proof feeding station or try one of the few hedgehog specific foods that are safe and relatively nutritious - brambles dry or semi moist, spikes dry (their semi moist contains high levels of sugar which rots teeth leading to death by starvation). Avoid any that have oats, fruit, seeds, nuts, honey, or insects. No bread or water, no fruit or veg.
