I found this:

Also called my vet and she said that as long as the pups don't have an iodine allergy or sensitivity, they should be fine dosed as a child (and added that she was going to need to research this further because she doesn't have anything "official" on this but that she had received a couple of calls about it since Sunday).
edited to add: child dosages would be based on the animal's weight and she is guestimating that 20mg would be plenty for a cat and that it would go up from there but she wants to confer with another vet before telling me anything "on the record".
Anyone have a vet they can ask too? Im curious what the consensus is?
