Spray vinegar on spot that cat like to mark to stop them doing so

For this past 2 weeks, we have been bombed with stink odor from cat pee which they do to mark their territory on our lab door.

This method already proven by my lab mate. As he have use it religiously for the past few months. Now, his shoe area and house is cat pee free already😉

Method: put the vinegar in spray bottle. Then spray the surface that cat always mark or poop there.
I choose this method as it is not harmful for my cats and safe for me also. Regardless the prickly vinegar scent😅
Feel free to try it also for weed control on your plants that being plant in a pot. As it would help your plants if it is use moderately. 

Till then, have a cat pee free zone💕
