Soiling On The Carpet

Dark dirt marks around the edges of your carpet are caused by an issue called filtration soiling.
Soiling on the carpet. Artificial turf or some discarded or shredded carpet might help to increase the appeal for cats that prefer to. If the area is badly soiled with urine over a long period it may be necessary to cut out the section of carpet and underlay and treat the concrete or floorboards underneath before replacing. If you have light colored carpeting these dark lines are more visible around the edges of your carpet and especially near the hvac returns heating and air. The first step to preventing filtration soiling is to be sure that your ducts are clean.
Problem behaviors can be urine and or stool deposited outside of the litter box or marking behaviors. Start with the hvac system. As the air is forced through the ventilation system it picks up whatever dirt is in the ducts and carries it into the living areas of the home and thus potentially into the carpet.

You may need to use detergent for more persistent stains. To clean up these stains you need water and vigorous scrubbing. Soiling is the result of a residue or oily substance on the carpet fibers which then attracts dirt particles. Filtration soiling occurs when there is an imbalance in the air ventilation of the room.
Filtration soiling are those dark lines or bands of soils that you can find along walls under doors that are kept closed for a length of time and under the skirting of furniture.
