For the cat porridge, first bring all the ingredients for the porridge to a boil and let it thicken for 5-10 minutes, stirring until the desired consistency is reached.
In the meantime, peel and slice kiwi, then cut out or trim crescents. Cut down a slice from the orange and quarter it. Wash triangles of blueberries.
Pour the finished porridge into a bowl. Place the kiwi crescents on top as eyes. Place two orange quarters on the top of the bowl with the peel facing the eyes. Make a mouth and snout from the blueberries on top of the porridge.
Serve cat porridge right away.
