We put it in either small chutney bowls or cake cases, and we make sure the porridge is fairly solid (or completely solid, they quite like it mixed with some bird seed and oven baked for a bit). Some hams still make a mess - like when Fwirl decided it was perfectly sensible to turn over a cake case of cat food and pull it to her nest with the cat food under the cake case, but that aside... Its not as messy as you'd expect lol
Oh, make sure the egg and porridge are cool before the hams get them too, they solidify more and are safer as there's no risk of hams burning themselves
