okay she must be marking her territory on an outside brick wall where I used to live so no damage. She doesn't have urgency and goes in the litter box. thanks
could also be a sign of a bladder infection &/or crystals and wouldn't hurt to get a urinalysis done at the Vets, could also check her anal glands.
cleaning the area with vinegar/water solution also needs baking soda and some 3% hydrogen peroxide added to the mix. if that doesn't work you can get some good enzyme cleaning solution at a good pet store..
Your cat is marking her territory. Best way to diminish this behavior is to wipe the area on the wall with a water and vinegar mixture: the smell will stop her from marking that spot again. ( mix water and vinegar 4:1, adjust strength as needed). Oh and try it on a not easily seen area first, just to be sure it does not damage your wall.
