A pet hedgehog’s diet centers on high-protein, low-fat dry food, supplemented with insects, small amounts of fruits and vegetables, and fresh water. The ideal nutritional profile on a dry-matter basis is 30% to 50% protein and 10% to 20% fat. Getting these ratios right is the single most important factor in keeping a hedgehog healthy and at a stable weight.
The Staple: Dry Cat Food or Hedgehog Kibble
Most hedgehog owners use high-quality dry cat or kitten food as the dietary staple. Hedgehog-specific commercial foods exist, but many contain wheat as a primary ingredient, which is essentially filler since hedgehogs can’t digest it well. A cat kibble with real meat listed as the first ingredient, protein in the 30% to 35% range, and fat around 10% to 15% tends to be a better choice than most marketed “hedgehog food.”
The daily portion is small: roughly 1 to 2 tablespoons of kibble per day, offered in the evening or at night when hedgehogs are naturally active. Because hedgehogs are prone to obesity in captivity, portion control matters more than it might seem for such a small animal. If your hedgehog is gaining weight, cut back slightly on kibble before reducing supplements.
Dry kibble also plays a role in dental health. The crunching action helps keep teeth relatively clean compared to soft food, which tends to promote plaque buildup. That said, very hard kibble (like large-breed dog food) can prematurely wear teeth down over time, so standard cat-sized kibble hits the right balance.
Insects: The Natural Protein Source
Hedgehogs are insectivores by nature, and offering feeder insects adds both nutrition and enrichment. Crickets and mealworms are the most widely available options. Gut-loaded insects (those fed nutritious food before being offered to your hedgehog) deliver better nutritional value than dried ones.
There’s an important caveat with mealworms, though. They have a calcium-to-phosphorus ratio between 1:7 and 1:11, which is far from the healthy target of roughly 1:1 to 2:1. When eaten in large quantities over time, this imbalance can actually strip calcium from a hedgehog’s body, leading to metabolic bone disease. Rescue organizations have documented hedgehogs arriving with soft, deformed bones from mealworm-heavy diets. Treat mealworms as an occasional snack, not a dietary cornerstone.
Insect exoskeletons contain chitin, a natural fiber-like substance that hedgehogs encounter constantly in the wild. Chitin is difficult to fully digest, but it appears to support gut health by promoting beneficial bacteria and may help modulate the immune system. This is one reason live insects are nutritionally superior to processed food alone.
Fruits, Vegetables, and Other Supplements
Small portions of fresh produce can be offered two to three times per week as supplements. Safe options include apples, pears, bananas, and cooked carrots. These should be cut into tiny pieces to prevent choking and offered in amounts small enough that they don’t replace the main kibble meal. Think of them as a garnish, not a side dish.
Hard-boiled egg is another good occasional protein boost, and some owners offer small pieces of cooked, unseasoned chicken. These protein supplements are especially useful for hedgehogs that are underweight or recovering from illness.
Foods to Avoid
Hedgehogs are opportunistic eaters and will happily consume things that are bad for them, so the responsibility falls entirely on you. Several common foods are genuinely dangerous:
- Dried fruits like raisins and sultanas can cause digestive problems and are too high in sugar.
- Nuts and seeds such as peanuts and sunflower hearts share the same calcium-to-phosphorus imbalance as mealworms (around 1:6 to 1:7), contributing to bone disease over time.
- Milk and dairy cause diarrhea because hedgehogs are lactose intolerant.
- Bread offers no nutritional value and can cause bloating.
- Raw meat carries a bacterial contamination risk that hedgehogs in captivity aren’t equipped to handle the way wild animals might.
The underlying pattern with most harmful foods is either a dangerous calcium-to-phosphorus ratio or ingredients hedgehogs simply can’t digest. When in doubt, stick to the safe list rather than experimenting.
Water and Hydration
Fresh water should be available at all times. The best option is a shallow, sturdy water bowl rather than a drip bottle. Bowls allow hedgehogs to drink more naturally and in larger quantities. Drip bottles are harder to clean thoroughly, which leads to bacterial buildup inside the tube and nozzle. The one downside of bowls is that food crumbs and bedding can fall in, so you’ll need to change the water daily.
Putting It All Together
A well-balanced hedgehog feeding routine looks like this: 1 to 2 tablespoons of high-quality, meat-based cat kibble served each evening, a few gut-loaded insects offered two to three times a week, and a small piece of fruit or cooked vegetable rotated in on those same supplement days. Fresh water in a bowl, changed daily. That’s the whole system.
Hedgehogs in captivity are highly prone to obesity, fatty liver disease, and dental problems, and all three are directly linked to diet. Keeping portions consistent, avoiding high-phosphorus snacks, and resisting the urge to overfeed treats will address the most common dietary health risks before they start.
