I am in the process of starting a cattery and need to know of safe products to clean my tub, commodes, sinks, etc. I know you have to be extremely careful because of them walking on these areas then licking their paws etc. Is comet safe?? Also, what do you mop your kitchens, bathrooms, etc. with? Also, do any of you use the ozone machines to keep down bacteria, URI's, odor, etc? What is your opinion and experiences with these. I have heard conflicting things about them. Thanks for your help.
