My cat coughs up fur balls and this yellow stuff along with it and the yellow stuff after I steam clean is still there lighter than what it was so how can I completely remove it?

Answer: We sure love our pets, but not their messes! For cat vomit and fur balls, I recommend blotting up excess liquid with a clean, absorbent cloth. Be aware that the acid in the vomit can permanently stain the carpet fibers. Generously and evenly spray the area with a BISSELL enzyme action product such as BISSELL Pet Stain & Odor Pre-treat for Carpet & Upholstery.  It has enzyme action that goes deep into the carpet and "eats" away the stain.  Per instructions, spray the stain, and then cover with a damp towel for up to 72 hours.  Then, use your BISSELL upright or portable deep cleaner over the affected area.

If there is any discoloration remaining from the stain, try BISSELL Stomp ‘N Go®, OxyPro® or OxyPro® Pet  and let stand overnight.
