The smell of cat urine can be very difficult to get rid of, especially on upholstery. Deterring your cat from urinating on your furniture will save you the chore of cleaning it or having to replace it. This is a guide about deterring cats from urinating on furniture.
I'm not going to tell you what the smell was like. All of you who have this problem know the odour too well!
I took in 3 feral cats and they decided that their litter box was going to be inside my Laz-Y-Boy recliner! They would crawl up inside it from the back, do their thing and sneak away. It took me quite a while to figure out where the stench was coming from. I solved this problem by flipping the chair upside down, vacuuming it thoroughly, scrubbing it with Lysol, and letting it dry. Then I filled a small spray bottle with mouthwash and sprayed every piece of wood in the frame, being careful not to get the metal parts wet. Then I went around and flipped over all the rest of my furniture and cleaned and sprayed it, as well.
This was about 3 weeks ago, and they have stopped using my furniture as a litter box. I actually saw one of them sneak out from behind their "safe hiding place" in a large dog crate, covered in blankets, and use the litter box. I can't put them back outside, due to our terrible winter weather, so I'm really happy with this solution. I hope this helps everyone else with this problem!
