Hi!
I don't know of anyone that has used CDS on cats. Most have used MMS. It required being sneaky in their food and a good supply of Band-Aids!
I use MMS in the room as a room air deodorizer. I just make a batch up in a shot glass and set it in the room where animals won't knock it over. I used 1 dropper each of MMS and citric acid to activate. I use it mainly in the bedroom and it works well there.
As far as dose goes, always start very small. Especially with an animal. Start at say 1/2 or 1/4 drop and work from there.
The animal thread should give you a lot of ideas.
