Cats aren't stupid they will feel the heat & stay away. My cats when kittens never went near it also the heat is intense & it's just too hot for them they would sooner rest further away...unlike my dog who lays in front roasting herself till she has to get up to rehydrate!!
If you're still worried when the stove is hot hold them in your hands near & open the door they will see & feel the danger.
