The cleaner I've been using is Bissell "Pet Stain & Odor" which is compatible with our Bissell steam cleaner. Is there a better cleaner someone can recommend instead? Also she is both peeing and pooping on the carpet. I take her outside to do her business and know that she's peed and pooped outside, but she's being very sneaky about this. She doesn't do it anywhere else in the house, and this only started a couple of months ago when I bought this new carpet

. I am putting the carpet away now, but I'm curious as to why she would start this in the first place.
