Hi Sapphire. I'm so sorry about your cat. I would definitely try the Humaworm for pets, and also coconut oil. I've heard of animals being cure of tumors with coconut oil. If you don't want to wait for the Humaworm, go to your health food store and buy black walnut extract, Wormwood extract, and oil of cloves and mix equal parts of each into her food. Try rubbing the coconut oil directly on her skin where the tumor is, if she will let you, and also give her about 3 teaspoons a day in her food if possible.
I can't promise it will save her, but it may prolong her life a little.
