We mix Cat wet food with the Hedgehog food (2 Löfffel hedgehogs feed on 1 spoon wet food) and had last year 6 hedgehog visits. The feeding station spoke at ease :) rum. The pretty dry hedgehog food we never feed exclusively, because we think the animals otherwise get too little liquid through the feed intake.
Our cats do not go ran to the Igeflutter with "denatured" (Cat) feed.
