Unfortunately you can’t as it’s part of having visitors such as hedgehogs but their is ways to make it harder for them but still allows hedgehogs in such as making the hole smaller, surprisingly hedgehogs are very agile and can tuck their body’s up very small to get into tight areas as rats and foxes and cats can’t….you may think god my hedgehog can’t fit in their but honestly you will be surprised
Hedgehogs feed late so later you put food out less time rats have to eat it, another thing to try is mint a little bit by the feeding station or growing near by should deter your rats they hate it I have tried it and it does work and hedgehogs apparently love the smell
Also try cat food (nothing fish based though as hedgehogs won’t eat it) as they apparently hate cat food
Hopefully these tips will help let me know how you get on
