No point of the bowl being raised is that while she is wearing the cone her tongue has to be able to reach the food and the water. So the food and water bowl (like in the picture on the site you posted above) would need to be able to fit under the cone when her head is bent down to eat and drink. If the bowls in their stand are wider than then outside diameter of the cone she won’t be able to reach the bowls. She does not need to be spoon fed. You just have to make sure that she cannot reach her stitches.
A lot of people on this site feed wet (canned) and dry (kibble) mixed together in the same meal.
