JR Garden Grain-Free Hedgehog Food

My usual hedgehog food supplier was out of stock so I ordered this one. Unfortunately none of my resident hedgehogs will eat it. I used to have an issue with Mr fox, crows and seagulls eating all their food next morning but not with this product for whatever reason.

Hedgehogs are pure insectivores; while this food is grain-free, it contains potatoes, potato flakes, beet pulp, yeast, birch leaves and much more. He only eats this food out of desperation, but he can't digest it. It's really sad in my opinion that some specialist shops or manufacturers still don't get this. I did buy it, but unfortunately didn't pay attention to the ingredients. I'd be glad if specialist shops stopped selling this kind of food.
