The supplemental feeding of wildlife is a worldwide phenomenon. The most widespread and socially accepted example is bird feeding. Commercial hedgehog (Erinaceus europaeus L.) diets are readily available in Switzerland. To test the hypothesis that commercial hedgehog diets are nutritionally inadequate, the following parameters (as taken from the label) of five commercial diets (three dry and two wet) were compared to the natural diet of E. europaeus: List of feed materials, crude ash (CA), crude protein (CP), crude fibre (CF), ether extract (EE) and nitrogen-free extracts (NfE). To test the second hypothesis, that feed labels of commercially available hedgehog diets in Switzerland are in accordance with Swiss and European law, the following parameters were assessed: Type of feed, net quantity, moisture content, instructions for proper use, list of the feed materials and claims. In all dry diets, the first ingredient was cereals (38.8%-50%), whereas in both wet diets, it was meat and meat by-products (51% in one product). Only one product had a CP content comparable to that of the natural diet and four products had a higher NfE content. Overall, the wet products were more comparable to the natural diet, especially regarding CP and NfE content. Of the five examined diets, three were labelled as complete feeds and two as compound feeds. The label analysis revealed inaccuracies and possible misleading information on two products. In conclusion, the use of commercial dry hedgehog diets should be discouraged as they do not resemble the natural diet of E. europaeus and are likely nutritionally inadequate. The commercial wet hedgehog diets should only be used supplementary. The feed labels of commercially available hedgehog diets were not always in compliance with Swiss and European law. The public should be educated about feeding E. europaeus and the risks of commercial diets for wildlife.
