I use Tracenet to prevent my 7 year old cat urine marking done on my leather armchair. This product has not stained my chair is already good! This product dédruit urine odor; and yet I can assure you that my urine is strong neutered kitty! The downside is that if I forget to spray Tracenet one day my cat will be quick to urinate again at the same place! I continue to see if spraying in time stop my cat!
