Foods I often use for my MC babies are baby foods mixed with some water, and a bit of oil on occaion. I also use rice baby cereal. It can be used on it's own, or as a thickener in water baby food. Other things you can try are melons like watermelon, or very ripe banana is good (nice and dark spotty all over!), as well as lettuce. If they're all girls, you can maybe give some orange segments with the skins taken off/pith taken off. When I bake chicken, I save some of the fat drippings and will add that to their food and let it melt with a little boiling water. It tastes great for them, and adds a little fat lubrication to the diet. What do you need MC diet for, just for gentleness on their tummies? Or do you need them to have softer poops? If you just want gentleness, you can blend your normal rat kibbles and soak the powder in boiled water to make a mush (to make sure they still are getting the nutrients), but also you can mix like plain boiled chicken pieces, baby food, and steamed white rice. Goat's yogurt or goat kefir might also help their tummies if you mix it all together and give it frequently.
I hope your girls will be ok! Is it not possible to just debulk the tumor if it's not able to be fully removed? They should still be able to remove most of it, even if they can't remove all of it, I would think.
