Re: MCS with cats...how do you get rid of cat pee smell on carpet

You have MCS and you have carpet? Hmmmm... most people who have MCS cannot have carpet in their house because the carpets have toxic chemicals including formaldehyde and glues and stain protector chemicals, and because they harbor dust and dust mites under them and in them.

I use plain clay kitty litter - no scent...no synthetic chemicals

Did you try vinegar and or baking soda to remove it?
