Re: Cat Breast Cancer
I would order either Utopia Silver colloidal silver or Mesosilver - they are the only true colloidal silver products I know of. Since time may be of the essence, I would get whatever your local health/supplement store has and use it until the good stuff arrives. Just use more of it. Kelp is OK, but it does not contain nearly as much iodine as say Lugols (or better still a combo of SSKI and Magnascent),
The Alpha Omega salve may work fine - they make good stuff for the most part, imo. It is likely to be painful though and you will need to shave your cat around the tumor so that you can cover and tape up the tumor with a bandage after applying the black salve.
You may wish to take a look at this as well:

Though it is written specifically for dogs, it also applies for the most part for cats as well (and it includes notations where items that are OK for dogs are not OK for cats - such as garlic for example).
I hope that your cat has enough time left and that all works out well:
